Abstract:

Alfalfa (Medicago sativa L.) is an important legume forage crop. However, its genetic improvement for salt tolerance is challenging, as alfalfa’s response to salt stress is genetically and physiologically complex. A review was made to update the knowledge of morphological, physiological, biochemical, and genetic responses of alfalfa plants to salt stress, and to discuss the potential of applying modern plant technologies to enhance alfalfa salt-resistant breeding, including genomic selection, RNA-Seq analysis, and cutting-edge Synchrotron beamlines. It is clear that alfalfa salt tolerance can be better characterized, genes conditioning salt tolerance be identified, and new marker-based tools be developed to accelerate alfalfa breeding for salt tolerance.

Abstract:

Winter survival of alfalfa (Medicago sauva L.) has often been associated with the size of the root system but breeding for a larger root system has never received much attention. The objectives of this study were to detect variability for root traits among seven alfalfa entries grown under two nitrogen fertilizer treatments (R- and N-treatments) which consisted of Rhizobium nitrogen fixation and inorganic nitrogen fertilizers, respectively; to select for root yield in two alfalfa cultivars grown under the same two treatments and to measure resulting progress; and to determine which of the two N regimes is more appropriate for root yield selection. Variability for root yield, number of laterals, crown width and top yield was found among R-treated entries whereas only the crown width varied among the N-treated ones. The evaluation under both treatments showed that one cycle of bidirectional phenotypic selection made under both the R- and N-treatments was sufficient to allow the formation of divergent populations for root yield with the exception of Apica-derived populations which showed inconsistent or no responses when evaluated under the N-treatment. Independently of the cultivars and treatments used for selection and evaluation, asymmetries of response were observed. Possible explanations are proposed but additional cycles of selection are needed to provide definitive conclusions. Indirect selection responses observed for top yield, crown width, and root branching should make selection for increasing root yield in alfalfa attractive. Key words: Medicago sativa L., root branching, realized heritability, asymmetry of response, indirect response

Abstract:

The main parameter of the breeding work with alfalfa in the ARC “Donskoy” is the improvement of fodder and seed productivity. Through the years the breeding work was carried out with 500–860 collection samples of alfalfa, alfalfa hybrids and alfalfa lines of the local origin. The main method of the breeding work was poly-crossing. It’s characterized with a multiple repetition of selections of the best plants from the populations, their self-pollination and crossing by free pollination in the plots of poly-crossing. It resulted in accumulation and concentration of favourable traits in the population. The selection promoted systematic improvement of synthetic populations according to economic-valuable traits, especially fodder and seed productivity. During the research, productivity of green mass of the standard variety ‘Rostovskaya 90’ was 28.2 t/ha in the first cutting and 19.0 t/ha in the second one on average. The varieties ‘Lyutsiya’ and ‘Selaynka’ produced 30.6 t/ha, 19.8 t/ha and 32.1 t/ha, 20.4 t/ha respectively. The sum of the harvested green mass of the standard variety was 47.2 t/ha, while ‘Lyutsiya’ produced 50.5 t/ha and ‘Selaynka’ 53.1 t/ha, that is on 7.0% and 12.5% larger than the standard. The similar result was obtained in productivity of dry matter. The total quantity of dry matter produced by the standard variety was 11.6 t/ha (two cuttings), the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 12.6 t/ha and 12.8 t/ha that is on 8.6% and 10.3% more than the standard. The estimation of the breeding work with alfalfa in the preliminary and competitive variety testing allowed to identify the new alfalfa variety ‘Golubka’ and to send it to the State Variety Testing. In the competitive variety testing (2012–2016) the variety produced larger yields that the standard variety (productivity of all five 1-st cutting). With its average productivity of green mass (31.9 t/ha) it exceeded the standard on 13.1%. In the 2-d cutting its green mass productivity was 20.9 t/ha that is on 10.9% more that the standard. With the average productivity of green mass the variety ‘Golubka’ produced 8.0 t/ha in the 1-st cutting and 4.9 t/ha in the 2-d, that is on 12.7% and 8.9% lager that that of the standard. The variety ‘Golubka’ produced 52.8 t/ha green mass for two cuttings and 12.8 t/ha dry matter that is on 11.9% and 10.3% larger than the standard variety ‘Rostovskaya 90’. Seed productivity of the standard variety was 0.23 t/ha on average, the varieties ‘Lyutsiya’ and ‘Selaynka’ gave 0.25 t/ha, the new variety ‘Golubka’ produced 0.29 t/ha, that is on 8.7 and on 26.1% more than the standard.

Abstract:

Abstract Novel alfalfa varieties have been developed to have less lignin by genetic modification, (HarvXtra, Forage Genetics International) and by conventional breeding, (HiGest 360, Alforex Seeds). Second crop (d 29) of these alfalfas and a control, LegenDairy XHD (Winfield Solutions LLC), were harvested as high moisture wrapped bales (45.9–51.6 % DM) at the Arlington Agricultural Research Station (AARS) located near Arlington, WI, on July 5, 2017. The objectives of these experiments were to characterize novel reduced-lignin alfalfa varieties, assess their effects on growth of beef steers, and determine digestibilities using a total fecal collection trial. Treatments were fed ad libitum as alfalfa baleage to 300 kg (initial weight) black-hided beef steers, (n = 72, 4 pens/treatment, 83 d). Steers were fed solely alfalfa baleage and offered a trace mineral salt block by way of fence line feed bunks. Alfalfa lignin values were 7.56, 7.18, and 6.3% DM (P = 0.34) for LegenDairy, HiGest and HarvXtra, respectively. Steers gained 0.94, 1.00, and 1.07 kg hd-1 d-1 (P = 0.25) for LegenDairy, HiGest and HarvXtra, respectively. The same harvested alfalfa was used in a total collection fecal trial with fecal collection bags (Table 1). Numerical differences between alfalfa digestibilities were observed but no significant treatment effects were detected. Total tract NDF digestibilities (TTNDFD) for harvested alfalfas were 33.9, 35.0 and 40.3 % NDF (P = 0.079) for LegenDairy, HiGest and HarvXtra, respectively. Alfalfa lignin concentration differences were not detected through acid detergent-lignin analysis of harvested bales. While the ranking of lignin concentrations, digestibilities, and growth rates followed prevailing logic, alfalfa variety treatment effects were not detected. Experimental designs with greater sensitivity should be implemented in the future.

Abstract:

Aim. Alfalfa is a rich source of phytoestrogens, among them coumestrol which shows strong estrogenic activity that can adversely affect the health of domestic animals. The aim of the study was to determine the variation in coumestrol content in leaves of alfalfa breeding populations, present in the breeding program of Agricultural Institute Osijek in Croatia. Method. Twelve alfalfa populations were selected based on their high forage yield and good persistence. Coumestrol was extracted using acidifi ed methanol as an organic solvent from lyophilized and ground alfalfa leaves, while for detection and quantifi cation was used. Results. Signifi cant differences were observed between the studied populations with average coumestrol content of 435.67 mg/kg of dry matter (DM). The highest content of coumestrol was determined in breeding population Rs-21 (619.53 mg/kg of DM). Conclusions. Populations Rs-33 and Rs-20 had the lowest coumestrol content (82.18 and 86.58 mg/kg, respectively) and present a potential breeding source for creat- ing new contemporary cultivars with decreased coumestrol content

Abstract:

Alfalfa is planted in more than 30 million hectares worldwide, but despite its popularity in temperate regions, it is not widely grown in subtropical agroecosystems. It is critical to improve alfalfa for such regions, considering current predictions of global warming and the increasing demands for animal-based products. In this study, we examined the diversity present in subtropical alfalfa germplasm and reported genetic parameters for forage production. An initial screening was performed from 2014 to 2016, evaluating 121 populations from different subtropical origins. Then, a breeding population was created by crossing selected plants, resulting in 145 full-sib and 36 half-sib families, which were planted in a row-column design with augmented representation of three controls (‘Bulldog805′, ‘FL99′ and ‘UF2015′). Dry matter yield (DMY), canopy height (AH), and percentage blooming (BLOOM) were measured across several harvests. Moderate narrow-sense heritability and high genetic correlations between consecutive harvests were estimated for all traits. The breeding line UF2015 produced higher DMY than FL99 and Bulldog805, and it could be a candidate cultivar release. Several families produced higher DMY than all checks, and they can be utilized to develop high yielding and adapted alfalfa cultivars for subtropical agroecosystems.

Abstract:

The objective of this paper was to assess the importance and effectiveness of progeny tests that can be used in alfalfa breeding for increased green forage yields and shoot number per plant. A total of 35 alfalfa genotypes of different geographic and genetic origins were analyzed. The results of the study have shown that crossing full-sib or half-sib parents leads to a significant increase in yield and shoot number per plant. Significant inbreeding depression was observed in the S1 progenies of all the genotypes involved. The choice of alfalfa parents must be based on progeny analysis. Which particular method will be used will depend on the objective of the breeding program.

Abstract:

This investigation examined the efficiency of various screening procedures which could be used in breeding for increased production of root-proliferating (RP) genotypes of alfalfa (Medicago sativa L. s. l.). Also investigated were relationships between RP and winter growth characteristics in populations derived from crosses between dormant, RP clones and nondormant, non-RP clones. In addition, this investigation also considered the inheritance of the RP habit. Plants from an 11-month F₁ progeny test containing 3508 offspring were qualitatively analyzed for RP expression using three pairs of screening procedures. Procedures compared included: (1) direct-seeding vs. transplanting; (2) use of characterized parental clones (known RP-expressing genotypes selected from field nursery) vs. uncharacterized parental clones (genotypes derived from RP seed lots with no prior knowledge of their ability to express the RP habit) in RP x nondormant crosses; and (3) low vs. high harvest frequencies. A low frequency (3.3%) of F₁ plants exhibited adventitious shoot formation. No differences were observed in the frequency of RP-expressing genotypes between the direct-seeded and transplanted treatments or between the low and high harvest frequency treatments. Characterized RP parents produced a hybrid population with a significantly higher frequency of RP-expressing genotypes than did the F₁ population derived from uncharacterized RP parents. Average winter forage production of the F₁ hybrids were similar in magnitude to the midparent value. Plant height was significantly and positively correlated with forage yield and could be used as an accurate indicator of winter forage yield in analyses of RP segregants. Estimates of components of genetic variance for RP expressivity indicated a predominance of additive effects and narrow sense heritability of 8.4%. Family selection and progeny testing are suggested for maximum breeding progress.

Abstract:

Regrowth and yield of 23 Middle Eastern (ME) cultivars and the elite cultivar Lew were evaluated for twelve regrowth harvests in pure stands and 50:50 mixtures with Lew in 1988 at Tucson, Arizona. Stem elongation rate and crown shoot development were measured on selected ME cultivars and Lew in the spring of 1988. No significant differences in yield were observed between mixtures and monocultures. Few significant differences were observed over all yields among ME cultivars and Lew. Cultivars from Saudi Arabia and Egypt produced more forage than Lew in spring harvests. These cultivars developed crown shoots precociously and had high stem elongation rates during the first week of regrowth. Most ME cultivars had higher leaf area and leaf:stem ratio than did Lew. These findings suggest that ME cultivars may be useful in improving forage yield during the winter and spring and forage quality in elite nondormant cultivars.

Abstract:

Thesis (MTech (Agriculture))--Cape Technikon, 1998.
The drymatter - and animal production of nine lucerne cultivars were evaluated under dryland conditions with SA Mutton Merino sheep at Outeniqua Experimental Farm (George). The nine lucerne cultivars that were chosen for this experiment, were already evaluated in cutting trials for their drymatter production. They consist of one winterdormant cultivar (Alfagraze), two semi-winterdormant cultivars (WL 320 and Meteor), five intermediate-winterdormant cultivars (SA Standard, Standard Tygerhoek, Aurora, Diamond and WL Southern Special) and one winteractive cultivar (Cuf 101). The mild climate of this area resulted mainly in a difference in drymatter production between the most winterdormant cultivar (Alfagraze) and winteractive cultivar (Cuf 101). The only difference in the rate of production of winterdormant types appear in winter and spring. The production rate of the winterdormant and semi-winterdormant cultivars was lower in the winter than that of the intermediate winterdormant (WL Southern Special) and the winteractive cultivar (Cuf 101). The drymatter production of the semi-winterdormant cultivar (WL 320) was higher than that of the winteractive cultivar (Cuf 101) in spring. There is a seasonal difference in the drymatter production of lucerne cultivars from the same winterdormancy class. Some of the more winterdormant cultivars also achieve a comparable and even higher dry matter production than that of the more winteractive cultivars. This tendancy is prominant between the semi-winterdormant cultivars (WL 320 and Meteor). WL 320 has a higher dry matter production than Meteor. It also has a higher or equal production rate, dependant on the seasons, than the winteractive cultivar (Cuf 101). A similar tendancy appears in the intermediatewinterdormant cultivar (WL Southern Special). The seasonal drymatter production and production rate of this cultivar are the same as that of Cuf 101. The appearance of annual grasses and weeds had a seasonal influence on the availability of dry matter and animal production. The grass production increases over the years resulting in up to 20% increase of the green matter during winter and spring. The grazing capacity of the winterdormant cultivar (Alfagraze) has increased during this seasonal grass production. The lucerne cultivar with the highest drymatter production rate and the highest seasonal dry matter production, also had the highest grazing capacity. The yearly and seasonal grazing capacity of WL 320, Aurora, WL Southern Special and Cuf 101 was generally higher than most of the other cultivars. This was also the most important reason for the high live mass increase with these cultivars.

Abstract:

There has been limited research on the rooting patterns of alfalfa. This information would be important in developing new germplasm sources that are more water efficient, salt tolerant and drought tolerant. Ten alfalfa varieties were evaluated for possible genetic control of rooting traits. Seedlings were grown hydroponically in a growth chamber. The cultivars evaluated showed a significant statistical difference for width of lateral root system and number of lateral roots. The variation in seedling rooting patterns is sufficient to warrant a selection program for improved lateral rooting patterns.

Abstract:

The performance of an alfalfa (Medicago sativa L.) population has been improved by recurrent selection for germination salt tolerance. However, recurrent selection may lead to increased inbreeding. Since alfalfa is subject to severe inbreeding depression, accumulation of inbreeding during the selection process may negatively affect performance. This experiment was designed to determine the effects of inbreeding on germination performance in alfalfa under saline and non-saline conditions. The germination performance of seed having three different levels of inbreeding as examined. No adverse effects of inbreeding were observed in non-saline conditions. Consistent (but nonsignificant) declining trends were observed in germination percentage in saline conditions as the level of inbreeding increased. Proportionately larger declines were observed between generations in germination speed and early seedling vigor. These results suggest heterozygosity in alfalfa may be maintained simultaneously while recurrent selection for germination salt tolerance is conducted. Moreover, reducing inbreeding during recurrent selection for germination salt tolerance may be more successful if germination speed index or early seeding vigor are used for the measurement.

Abstract:

It was found that with an increase in the content of crude fiber, dry matter and soluble sugars by 1%, the buffer capacity of alfalfa dry matter decreases by 0.04–0.10, 0.09–0.19 and 0.16–1.44 mol/l, respectively. An increase in the content of crude protein, crude ash and crude fat by 1 % increases the buffer capacity of dry matter by 0.07–0.40, 0.19–86 and 0.33–1.11 mol/l, respectively. Therefore, to create alfalfa varieties with a reduced buffer capacity without appreciable damage to the feed value, it is necessary to conduct breeding to increase the content of soluble sugars and, possibly, reduce the content of raw fat.

Abstract:

The article describes the main morphological and biological features of alfalfa varieties included in the State register of breeding achievements approved for use in the Central Chernozem zone of Russia. A total of 32 alfalfa varieties are included in the State register. This is 9 varieties of blue alfalfa (Medicago sativa L. subsp. Sativa) of domestic selection and 8 foreign, 11 varieties of variable alfalfa (Medicago sativa L. nothosubsp. varia (Martyn) Arcang.) domestic selection and 1 variety of foreign and 3 varieties of yellow alfalfa (Medicago sativa L. subsp. falcata (L.) Arcang.). It shows the average and maximum yield of varieties determined in the process of state variety testing, as well as independent evaluation in research institutions in the region. Varieties of blue alfalfa of domestic selection Kevsala, Elena, Satellite, Vavilovskaya Yubileynaya were the most productive. The average yield of dry matter of these varieties reaches 8.4–9.2 t/ha, the maximum — 15.3–17.7 t/ha. Alfalfa varieties Timbale and Galaxy were the most productive among foreign varieties: the average yield of dry matter was 8.1 and 8.3 t/ha, the maximum – 15.5 and 17.2 t/ha. Varieties of alfalfa variable Vitalina and Vela provided an average yield of dry matter of 7.6 and 9.0 t/ha, the maximum yield reached 15.4 and 18.1 t/ha.

Abstract:

15 populations of black medic (Medicago lupulina L.) of various ecological and geo-graphical origin were studied by the type of ontogenesis. It was found that 1 population is represented entirely by monocarp forms of plants, 7 populations have 20–60% of mono-carps. Wild alfalfa from the Moscow region and mutant forms created on its basis consist of 100% bicarpic plants. Bicarpic plants of varieties Georgia, Nordol, Rinata and selection number LH19-3, whose average dry matter productivity was 40.8–48.0 g/plant, are valuable as a source material for breeding of black medic. As sources of high seed prod-uctivity (10.0 and 10.3 g/plant), you can use bicarpic plants of the selection number VIK 256 and Georgia varieties, and high leafed (52.4 and 55.3%) — selection numbers DS-1 and VIK 61/94.
