Abstract:
Water and heat stressors during flowering are predominant limitations of dryland sorghum yields across Australia’s north-eastern cropping zone. Crops sown early could flower before seasonal heatwaves, but the seed must uniformly germination and emerge at soil temperatures between approximately 10 to 15 °C. Furthermore, chemical coatings applied to commercial hybrid seed lots effectively protected the developing crop from pest, disease and herbicide damage but the combined influence of low temperatures and seed coatings on germination of hybrid sorghum seed batches is unknown. In this experiment, germination dynamics were modelled for 10 commercial sorghum hybrid-seed lots (with or without seed coating of a.i. thiamethoxam, oxabetrinil and thiram) incubated at continuous temperatures ranging from 9.4 to 46.1 °C. Results also show commercial seed treatments negatively affect final germination proportion especially at sub- and supra-optimal temperatures. Some hybrid-seed lots in current experiment were more sensitive to seed coatings at either sub- or supra-optimal temperatures regardless of seed germination capability (i.e., germination proportion at 25 °C). Seeds took 5 days to reach 50% germination (t50) at 9.4 °C but germinated within 24 h at constant temperatures between 20 and 40 °C. The spread of germination (time between 10 and 90% germination) increased from 0.5 days at 30 °C to 3.8 days at 9.4 °C. Therefore, some hybrid-seedlots are suited to early sowing because they can maintain high germination proportion (>90%) even at soil temperatures (9.4 °C) as long as the seedbed remains moist for a least 12 days. Research continues identify the basis of cold tolerance in some-hybrid seedlots.

Abstract:
The study involved the stability analysis of the parents and hybrids, using line x tester mating design. Twenty four hybrids along with their ten parents and checks ((SSG 59-3 and MFSH 4)) were evaluated at two locations with two dates of sowing (Early and late sowing) during the kharif season of 2015-16 for quality traits. Data on different qualiitative characters at first cut (55 days after sowing) and second cut (45 days after first cut) were recorded. Stable hybrids are desirable for commercial exploitation over a wide range of agro-climatic conditions. It is clear that mean sum of squares due to genotypes for all the characters were highly significant when tested against pooled deviation, which revealed that the hybrids had significant differences in response to varying environmental conditions. Five hybrids were found to have both bi and ¯Sdi2 significant, indicating the presence of both linear and non-linear components of G × E interaction for protein content. Hybrids 56A × IS 2389 was found stable, average responsive and suitable for all the test environments for IVDMD. The cross combination of 14A × HJ 513, 31A × HJ 541 and 14A × IS 2389 were found stable, average responsive and suitable for all the test environments for HCN content. On the otherhand, hybrids 465A × G 46 and 465A × IS 2389 and parent G 46 were found highly responsive and suitable for the favourable environments. Therefore, these hybrids can be utilized in further genetic study in future in plant breeding.

Abstract:
Nitrogen merupakan unsur hara esensial tanaman yang diperlukan paling banyak dibandingkan unsur hara lainnya. Namun demikian, pemberian pupuk N secara terus menerus berdampak pada menurunnya daya dukung lahan. Zeolit yang dapat digunakan untuk mengefisiensikan penyerapan N. Penelitian bertujuan untuk mengkaji dampak pemberian zeolit pada berbagai taraf pemberian N pada tanaman sorgum dilakukan dari bulan April hingga Juli 2017 di lahan sawah Desa Sumberduren, Kabupaten Kediri, menggunakan Rancangan Petak Terpisah dengan menempatkan dosis pupuk N (50%, 100% dan 150%) pada petak utama, dan dosis zeolit (0%, 50%, 100% dan 150%) pada anak petak yang diulang 3 kali. Ada tidaknya interaksi atau pengaruh nyata menggunakan Uji F taraf 5% dan dilanjutkan Uji BNJ taraf 5% untuk mengetahui perbedaan diantara perlakuan. Hasil penelitian menunjukkan dosis N 50% pada zeolite 150% mendapatkan hasil biji sorghum sebesar 3,32 t ha-1. Adapun dosis N 100% dan 150 % mengurangi penggunaan zeolite sebesar 43,5% dan 48,12% dengan hasil biji sorghum sebanyak 4,56 t ha-1 dan 5,15 t ha-1. Aplikasi 50% dan 100% zeolit dapat menekan penggunaan N sebesar 13,67% dan 16,19%.ABSTRACTNitrogen is an essential nutrient and needed in the highest amount compared to other elements. However, the continuous use of nitrogen causes a decrease in the carrying capacity of the land. Therefore to anticipate these problems, zeolite applications is prior to be done. The study aimed to assess the effect of N and zeolite application on sorghum plants which had been carried out from April to July 2017 in paddy fields in Sumberduren Village, Kediri Regency. Split Plot Design was used in this study by placing N fertilizer doses (50%, 100% and 150%) as the main plot, and zeolite dosage (0%, 50%, 100% and 150%) on subplots repeated 3 times. F test at 5% was used to determine the effect of treatments, while the average difference between treatments were referred to HSD value at 5%. The using of 100% and 150% N dosages could reduce the zeolite usage about 43.5% and 48.12% with sorghum yield as much as 4.56 t ha‐1 and 5.15 t ha-1 respectively. However, with the application of 50% and 100% zeolite, it can reduce N use by 13.67% and 16.19%.

Thesis (M. Tech. (Agric. Animal Prod.)) -- Central University of technology, Free State, 2009
The objective of this study was to evaluate the viability of semen extended in “Umqombothi” (UMQ) and compare with Beltsville Thawing Solution (BTS) and unextended semen (UNX). Twelve large white boars and twelve large white sows were used in this experiment. The following sperm characteristics were measured; sperm motility percentage, live sperm, sperm concentration, abnormal sperm percentage and semen pH of (UNX), (UMQ) and (BTS) and compared, fertility parameters namely; non-return rate percentage, farrowing rate, total piglets and live piglets were also measured and compared. The results from the study showed a significant difference (p<0.05) in sperm motility between (UNX), (UMQ) and (BTS) whereby (UMQ) had the highest percentage of motile sperm which was followed by (BTS) and (UNX) having the lowest percentage of motile sperm, however the results also showed that sperm motility and live sperm percentage of semen stored at 4°C differed significantly (p<0.05) from sperm motility and live sperm percentage of semen stored at 25°C whereby sperm motility and live sperm percentage of semen stored at 25°C were higher than sperm motility and live sperm percentage of semen stored at 4°C. Nevertheless no significant difference in sperm concentration and semen pH was found when semen stored at 4°C and 25°C were compared. However were time of semen collection of 9:00 and 15:00 were compared no significant differences in sperm motility percentage, live sperm percentage, sperm concentration, abnormal sperm percentage and semen pH were observed. The study also revealed a significant difference (p<0.05) in non-return rate, farrowing rate, total piglets and live piglets between semen stored at 25°C and 4°C of which the results explain that semen stored at 25°C had a higher percentage of non-return rate , farrowing rate, total piglets and live piglets, however, Under (UNX) collected at 9:00 and 15:00 that there was no significant difference in no-return rate percentage, farrowing rate, total piglets and live piglets was observed when two times of semen collections were compared. Under (UMQ) collected at 9:00 and 15:00 there was also no significant difference in non-return rate percentage, farrowing rate, total piglets and live piglets observed when two times of semen collections were compared. Under (BTS) collected at 9:00 and 15:00 there was also no significant difference in non-return rate percentage, farrowing rate, total piglets and live piglets observed when two times of semen collections were compared. Nevertheless were semen extenders were compared (UNX) collected at 9:00 and 15:00 differed significantly (p<0.05) from (UMQ) and (BTS) collected at 9:00 and 15:00 whereby (UNX) had the lowest percentage of non-return rate, farrowing rate, total piglets and live piglets.

Abstract:
En 1996, la FAO a reconnu le rôle des agriculteurs dans la construction des ressources génétiques. Dans ce contexte, l'objectif général du projet PLANTADIV, dans lequel s'inscrit cette thèse, est d'appréhender comment les facteurs anthropiques et biologiques interagissent et façonnent la diversité génétique des plantes cultivées dans le bassin du lac Tchad. Dans cette région, les populations ont mis au point une innovation agricole originale : l'utilisation en contre-saison de terres argileuses inondées pour repiquer du sorgho. Les variétés de sorgho repiqué sont capables de puiser dans les réserves hydriques du sol pour accomplir leur cycle végétatif en saison sèche sans autre apport d'eau. Le sorgho repiqué connaît un large développement dans la région depuis la moitié du XXe siècle. Le projet de thèse se focalise sur l'estimation de la diversité génétique des sorghos repiqués et sur les mécanismes biologiques et génétiques qui ont pu contribuer à sa structuration intra et inter variétale. Nous avons également entrepris de retracer l'histoire évolutive des sorghos repiqués en nous appuyant essentiellement sur des outils de génétique des populations pour discuter les hypothèses géographiques et historiques existantes. Cette étude a mis en évidence qu'au moins deux événements de dessaisonalisation avaient eu lieu à partir de sorghos pluviaux provenant de deux groupes génétiques différents. Les sorghos repiqués sont plus différenciés que les sorghos pluviaux. Ceci peut s'expliquer en partie par les pratiques paysannes : les sorghos pluviaux sont échangés plutôt via les amis, la famille et les voisins, alors que les sorghos repiqués le sont plutôt via les marchés. De par les nombreux échanges de semence entre les différentes populations humaines dans cette région, l'étude phylogénétique n'a pas permis de mettre en évidence le(s) lieu(x) d'origine de dessaisonalisation.La seconde partie de ce travail a été consacré à la biologie de la reproduction du sorgho repiqué. Les méthodes de calcul indirectes et directes ont montrées que le sorgho repiqué est, comme le sorgho pluvial, préférentiellement autofécondé. Le taux moyen chez le sorgho repiqué est cependant plus faible (1,8%) que pour le sorgho pluvial (12%). De même, les variations d'allofécondation entre des panicules d'un même type nommé semblent plus faibles que pour le sorgho pluvial. La dernière partie de la thèse est consacrée aux impacts des pratiques agricoles sur la structuration de la diversité génétique des sorghos repiqués à une échelle locale. Les analyses génétiques ont montré, que ce soit pour le village de Djongdong ou celui de Bouzar, situés à l'extrême Nord du Cameroun, que pour un agriculteur donné, chaque type nommé correspond à une entité génétique. De plus, un même morphotype chez différents agriculteurs correspond aussi à une entité génétique. Les modes de gestion des semences et les pratiques culturales ont été analysés, elles influencent peu la structuration de la diversité génétique du sorgho repiqué
In 1996, FAO has recognized the role of farmers in building and managing genetic resources. This work is part of the project PLANTADIV which main objective is to understand how biological and anthropogenic factors interact and shape diversity of cultivated plants in the Lake Chad Basin. In this region, people have developed an original agricultural innovation: the use in dry-season of flooded clay soils for transplanting sorghum. Transplanted sorghum varieties are able to tap into soil moisture reserves to complete their growth cycle in the dry-season without any water supply. Transplanted sorghum cultivation undertook a large development in the region since the middle of the XX century.The thesis project focuses on the estimation of the genetic diversity of planted sorghum and on biological and genetic mechanisms that may have contributed to its structuration both within and between landraces. We also undertook to trace the evolutionary history of planted sorghum by relying primarily on population genetics approaches to elaborate over geographical and historical hypotheses.This study revealed that at least two events of deseasonalization occurred from rain- sorghum pools from two different genetic groups. Differentiation of dry-season sorghum is stronger than that of rain-sorghum. This may be partially due to social practices: rainy sorghum are mainly exchanged through friends, families and neighbors as planted sorghum seeds are often obtain from markets. Extensive seed exchange between different human populations across the region may have blurred the geographical pattern of the genetic diversity, not allowing us to identify potential sites for deseasonalization.The second part of this work is devoted to the reproductive biology of dry-season sorghum. Direct and indirect estimation methods have shown that dry-season sorghum is, as rain sorghum, preferably selfing. Average level of out crossing is nevertheless lower in dry-season sorghum (1.8%) than it is in rain-sorghum (12%). Within landraces, variations are also smaller for dry-season sorghum than for rain-sorghum.The last part of the thesis is devoted to the impacts of agricultural practices on the structure of the genetic diversity of dry-season sorghum at a local scale. Genetic analyzes have shown that in both studied villages of Djongdong and Bouzar, located in the extreme north of Cameroon, each landrace named by a farmer corresponds to a genetic entity. In addition, the same morphological type among different farmers corresponds to a genetic entity. Modes of seed management and cultural practices were analyzed; they seem to have little influence on the structure of the genetic diversity of dry-season sorghum

Cold temperature stress is an important abiotic constraint to grain sorghum production in temperate regions. In the United States, low temperature in late spring and early fall has limited sorghum production to a narrow growing period. Deployment of cold tolerance traits may widen this window and hence contribute to increased production. The objectives of this study were (1) to determine the effect of early and mid-season cold temperature stress on growth, phenology and yield components of sorghum, and identify key traits that are most sensitive to cold stress at seedling and flowering stages, and (2) to identify new sources of cold tolerance for use in breeding programs. Series of controlled environment (greenhouse/growth chamber) and field experiments were carried out. Three sorghum genotypes of variable response, Shan Qui Red (tolerant), SRN39 (susceptible) and Pioneer 84G62 (unknown) were subjected to cold (15/13ºC day/night) and normal (25/23ºC day/night) temperature at seedling (Experiment I) and flowering (Experiment II) stages. The genotypes were planted in a greenhouse using a 5L polytainer pots. Each pot consisted of a single plant and each plot was represented by three pots. A split-plot design with three replications was used in both experiments with temperature regimes as main plots and genotypes as sub-plots. Three days after emergence, experiment I plants were moved to the growth chamber and subjected to the designated temperature treatments. For experiment II, the treatments were assigned at heading stage immediately before anthesis had begun. The treatments lasted 10 d in both experiments. Data were collected on seedling characteristics and leaf chlorophyll content in experiment I, days to flowering, maturity, and yield components in both experiments, and anthesis duration in experiment II. For the field experiment, 150 sorghum germplasm collections of potential cold tolerance along with tolerant and susceptible checks were evaluated for emergence and seedling traits under early planting (April 13) at soil temperature of 20.1/13.4 ºC max/min. The normal temperature treatment was applied by planting at regular season (May 26) at soil temperature of 30.0/20.4ºC max/min. Twenty-four genotypes selected based on field emergence and seedling vigor were further screened under controlled environment. Early-season stress significantly reduced leaf chlorophyll content, all seedling traits (height, vigor and dry weight), and also delayed flowering and maturity. But it had no effect on final leaf number, plant height and yield components. Genotypic response to early stress was significant for all traits with the susceptible checks having the lowest score for all seedling traits. Mid-season cold stress prolonged anthesis duration, delayed maturity and highly reduced all yield components. Several genotypes among the 150 had higher seedling vigor and emergence than the tolerant check, Shan Qui Red. In conclusion, reduced seedling vigor as a result of early stress had no effect on final yield provided that stand establishment was not compromised while mid season stress is damaging to yield. The wide genetic variation for the traits indicates the potential for improvement of cold tolerance in sorghum.

Abstract:
Sorghum (Sorghum bicolor (L.) Moench) is the world’s fifth major cereal crop and holds importance as a construction material, food and fodder source. More recently, the potential of this plant as a biofuel source has been noted. Despite its agronomic importance, the use of sorghum production is being constrained by both biotic and abiotic factors. These challenges could be addressed by the use of genetic engineering strategies to complement conventional breeding techniques. However, sorghum is one of the most recalcitrant crops for genetic modification with the lack of an efficient tissue culture system being amongst the chief reasons. Therefore, the aim of this study was to develop an efficient tissue culture system for establishing regenerable embryogenic cell lines, micropropagation and acclimatisation for Sorghum bicolor and use this to optimise parameters for genetic transformation via Agrobacterium-mediated transformation and microprojectile bombardment. Using five different sorghum cultivars, SA281, 296B, SC49, Wray and Rio, numerous parameters were investigated in an attempt to establish an efficient and reproducible tissue culture and transformation system. Using immature embryos (IEs) as explants, regenerable embryogenic cell lines (ECLs) could only be established from cultivars SA281 and 296B. Large amounts of phenolics were produced from IEs of cultivars, SC49, Wary and Rio, and these compounds severely hindered callus formation and development. Cultivar SA281 also produced phenolics during regeneration. Attempts to suppress the production of these compounds in cultivars SA281 and SC49 using activated charcoal, PVP, ascorbic acid, citric acid and liquid filter paper bridge methods were either ineffective or had a detrimental effect on embryogenic callus formation, development and regeneration. Immature embryos sourced during summer were found to be far more responsive in vitro than those sourced during winter. In an attempt to overcome this problem, IEs were sourced from sorghum grown under summer conditions in either a temperature controlled glasshouse or a growth chamber. However, the performance of these explants was still inferior to that of natural summer-sourced explants. Leaf whorls, mature embryos, shoot tips and leaf primordia were found to be unsuitable as explants for establishing ECLs in sorghum cultivars SA281 and 296B. Using the florets of immature inflorescences (IFs) as explants, however, ECLs were established and regenerated for these cultivars, as well as for cultivar Tx430, using callus induction media, SCIM, and regeneration media, VWRM. The best in vitro responses, from the largest possible sized IFs, were obtained using plants at the FL-2 stage (where the last fully opened leaf was two leaves away from the flag leaf). Immature inflorescences could be stored at 25oC for up to three days without affecting their in vitro responses. Compared to IEs, the IFs were more robust in tissue culture and showed responses which were season and growth condition independent. A micropropagation protocol for sorghum was developed in this study. The optimum plant growth regulator (PGR) combination for the micropropagation of in vitro regenerated plantlets was found to be 1.0 mg/L BAP in combination with 0.5 mg/L NAA. With this protocol, cultivars 296B and SA281 produced an average of 57 and 13 off-shoots per plantlet, respectively. The plantlets were successfully acclimatised and developed into phenotypically normal plants that set seeds. A simplified acclimatisation protocol for in vitro regenerated plantlets was also developed. This protocol involved deflasking in vitro plantlets with at least 2 fully-opened healthy leaves and at least 3 roots longer than 1.5 cm, washing the media from the roots with running tap water, planting in 100 mm pots and placing in plastic trays covered with a clear plastic bag in a plant growth chamber. After seven days, the corners of the plastic cover were opened and the bags were completely removed after 10 days. All plantlets were successfully acclimatised regardless of whether 1:1 perlite:potting mix, potting mix, UC mix or vermiculite were used as potting substrates. Parameters were optimised for Agrobacterium-mediated transformation (AMT) of cultivars SA281, 296B and Tx430. The optimal conditions were the use of Agrobacterium strain LBA4404 at an inoculum density of 0.5 OD600nm, heat shock at 43oC for 3 min, use of the surfactant Pluronic F-68 (0.02% w/v) in the inoculation media with a pH of 5.2 and a 3 day co-cultivation period in dark at 22oC. Using these parameters, high frequencies of transient GFP expression was observed in IEs precultured on callus initiation media for 1-7 days as well as in four weeks old IE- and IF-derived callus. Cultivar SA281 appeared very sensitive to Agrobacterium since all tissue turned necrotic within two weeks post-exposure. For cultivar 296B, GFP expression was observed up to 20 days post co-cultivation but no stably transformed plants were regenerated. Using cultivar Tx430, GFP was expressed for up to 50 days post co-cultivation. Although no stably transformed plants of this cultivar were regenerated, this was most likely due to the use of unsuitable regeneration media. Parameters were optimised for transformation by particle bombardment (PB) of cultivars SA281, 296B and Tx430. The optimal conditions were use of 3-7 days old IEs and 4 weeks old IF callus, 4 hour pre- and post-bombardment osmoticum treatment, use of 0.6 µm gold microparticles, helium pressure of 1500 kPa and target distance of 15 cm. Using these parameters for PB, transient GFP expression was observed for up to 14, 30 and 50 days for cultivars SA281, 296B and Tx430, respectively. Further, the use of PB resulted in less tissue necrosis compared to AMT for the respective cultivars. Despite the presence of transient GFP expression, no stably transformed plants were regenerated. The establishment of regenerable ECLs and the optimization of AMT and PB parameters in this study provides a platform for future efforts to develop an efficient transformation protocol for sorghum. The development of GM sorghum will be an important step towards improving its agronomic properties as well as its exploitation for biofuel production.

Abstract:
Sorghum is a staple food in the semi-arid tropics of Asia and Africa, sustaining the lives of the poorest rural people. This project set out to improve the potential economic value of Sorghum bicolor as a crop. The task was undertaken by screening for selected enzymes in the plant that would have a potential market for use in industrial applications and in biotransformations, specifically proteases, polyphenol oxidases and peroxidases. Asurveywas conducted using standard enzyme assays and crude plant extracts, to determine whether the selected enzymes were present. Grain tissue did not appear to have significant protease or polyphenoloxidase activity, but high levels of peroxidases were detected, withthe young grain extracts showing more activity(4.63U/mL)thanripegrain extracts (0.62 U/mL). Leaf tissue extracts contained low levels of protease activity, a considerable amount of polyphenol oxidase (0.127 U/mL), and peroxidase (4.7 U/mL) activities comparable with that found in grain tissue. Root tissue extract was found to contain the highest levels of peroxidase activity (7.8 U/mL) compared to the other extracts. Therefore, sorghum peroxidase from the root was isolated, purified, characterized and applied to biotransformation reactions. Different sorghum strains,withvaryinggraincolour, (Zimbabwe - bronze, Seredo - brown and Epurpur - cream/white) were investigated for the presence of polyphenol oxidase and peroxidase activities. Results of spectrophotometric analysis showed that the enzymes did not appear to be strain specific. However, gel electrophoresis analysis revealed differences in band patterns among the strains. Partial purification of sorghum root peroxidase was achieved after centrifugation, extraction with polyvinylpolypyrrolidone (PVPP), ultrafiltration, and hydrophobic chromatography with phenyl Sepharose, followed by polyacrylamidegelelectrophoresis (PAGE). The specific activity of the 5-fold purified enzyme was found to be 122.3 U/mg. After PAGE analysis, two bands with molecular weights of approximately 30 000 and 40 000 were detected, which compares well with horse radish peroxidase (HRP) which has a molecular weight of approximately 44 000. The colour intensity of the bands in the activity gels indicated that sorghum root peroxidase had apparently higher levels of peroxidase activity than commercial horseradish peroxidase (HRP). Characterizationexperiments revealed that sorghumroot peroxidase is active over a broad temperature range and remains active at temperatures up to 100°C. It also has a broad substrate range. The optimum pH of the enzyme was found to be pH 5 - 6. Under standardized assay conditions, the optimal substrate concentration, using o-dianisidine as substrate, was 50 mM, and the optimal H2O2 concentration under these conditions was found to be 100 mM. Sorghum root peroxidase was applied in a preliminary investigation into the oxidative biotransformationof a number of aromatic compounds. The products obtained were comparable withthose whenthe compounds are reacted with HRP which is the most commonly used commercial peroxidase and has been extensively studied. However, HRP is relatively costly, and the use of peroxidase from sorghum roots as an alternative source, appears to be promising. A patent has been provisionally registered, covering application of sorghum root peroxidase for biotransformations.

Abstract:
Physiological responses of 12 sorghum (Sorghum bicolor L.) genotypes previously classified as drought resistant and susceptible upon grain yield basis were evaluated under dry and wet moisture treatments at Tucson, Arizona in 1983. In addition, the relationship of these physiological responses and their heritability estimates were also determined. Apparent photosynthesis, transpiration, diffusive resistance, temperature differentials, and leaf temperature were measured under field conditions at three intervals from planting date: 48, 62, and 77 days, respectively. Stomatal density and epicuticular wax content were determined toward the end of the season when full canopy development was reached. Stress significantly affected all characteristics measured for each genotype by a reduction in apparent photosynthesis rates, transpiration, and temperature differentials, and an increase in diffusive resistance, leaf temperature and stomatal density. The wax content response varied among genotypes irrespective of the dry and wet moisture treatments. Except for the wax content and stomatal density, all the other parameters demonstrated a high significant correlation with photosynthesis at .001 level; nevertheless, greater values were observed in the stress treatment. Analysis of variance failed to detect significant differences among the 12 germplasm sources, except for the stomatal density. Multiple regression analysis showed that leaf diffusive resistance was the first variable incorporated for photosynthesis prediction in both the dry and wet treatments. The offspring and mid-parent regression for each characteristic under both treatments provided heritability estimates (h('2) (+OR-) SE), indicating higher heritability values under the dry treatment.

Abstract:
A criterion for assessing the activity of biochemical and microbiological processes in the rhizosphere is necessary to explain the direction of the reaction of organisms, communities or ecosystems in response to anthropogenic influences. The purpose of the research is to assess the influence of farming systems (traditional and no-till) and the complex of microbial preparations (СMP) together with arbuscular mycorrhizal fungi (AMF) on microbiological processes in the rhizosphere of S. bicolor using the integral indicator of the biological condition (IIBC). Using IIBС, the direction of biological processes in the sorghum’s rhizosphere was shown. It depended both on the cultivation technology and the use of microbial preparations. IIBС of rhizosphere increased by 9.1% when using CMP and AMF in no-till, which indicated an increase in the biological activity of sorghum plants.

Full text
Abstract:
Heterosis, the enigmatic phenomenon in which whole genome heterozygous hybrids demonstrate superior fitness compared to their homozygous parents, is the main cornerstone of modern crop plant breeding. One explanation for this non-additive inheritance of hybrids is interaction of alleles within the same locus. This proposal aims at screening, identifying and investigating heterosis trait loci (HTL) for different yield traits by implementing a novel integrated mapping approach in Sorghum bicolor as a model for other crop plants. Originally, the general goal of this research was to perform a genetic dissection of heterosis in a diallel built from a set of Sorghum bicolor inbred lines. This was conducted by implementing a novel computational algorithm which aims at associating between specific heterozygosity found among hybrids with heterotic variation for different agronomic traits. The initial goals of the research are: (i) Perform genotype by sequencing (GBS) of the founder lines (ii) To evaluate the heterotic variation found in the diallel by performing field trails and measurements in the field (iii) To perform QTL analysis for identifying heterotic trait loci (HTL) (iv) to validate candidate HTL by testing the quantitative mode of inheritance in F2 populations, and (v) To identify candidate HTL in NAM founder lines and fine map these loci by test-cross selected RIL derived from these founders. The genetic mapping was initially achieved with app. 100 SSR markers, and later the founder lines were genotyped by sequencing. In addition to the original proposed research we have added two additional populations that were utilized to further develop the HTL mapping approach; (1) A diallel of budding yeast (Saccharomyces cerevisiae) that was tested for heterosis of doubling time, and (2) a recombinant inbred line population of Sorghum bicolor that allowed testing in the field and in more depth the contribution of heterosis to plant height, as well as to achieve novel simulation for predicting dominant and additive effects in tightly linked loci on pseudooverdominance. There are several conclusions relevant to crop plants in general and to sorghum breeding and biology in particular: (i) heterosis for reproductive (1), vegetative (2) and metabolic phenotypes is predominantly achieved via dominance complementation. (ii) most loci that seems to be inherited as overdominant are in fact achieving superior phenotype of the heterozygous due to linkage in repulsion, namely by pseudooverdominant mechanism. Our computer simulations show that such repulsion linkage could influence QTL detection and estimation of effect in segregating populations. (iii) A new height QTL (qHT7.1) was identified near the genomic region harboring the known auxin transporter Dw3 in sorghum, and its genetic dissection in RIL population demonstrated that it affects both the upper and lower parts of the plant, whereas Dw3 affects only the part below the flag leaf. (iv) HTL mapping for grain nitrogen content in sorghum grains has identified several candidate genes that regulate this trait, including several putative nitrate transporters and a transcription factor belonging to the no-apical meristem (NAC)-like large gene family. This activity was combined with another BARD-funded project in which several de-novo mutants in this gene were identified for functional analysis.
