Abstract:
Protoplast culture (protoplast fusion) is one method of tissue culture that is widely used in plant breeding programs in a relatively short time. This method is used to overcome the problem of plants that are difficult or impossible to cross conventionally as well as used for species improvement by transferring the desired gene from the donor plant to the target plant via protoplast fusion. Protoplast fusion makes it possible to produce plants that are resistant to a disease and various abiotic stresses, rapid growth rates and have a better quantity and quality of metabolites than their parents. Various factors affect the success of fusion and regeneration of protoplasts into whole plants, including the source of explants, the composition of the enzyme solution and the duration of incubation, fusagen type and culture media for regeneration.

Abstract:
Biotechnology strategies are now available to improve the amount and availability of nutrients in plant crops. Those strategies include simple plant selection for varieties with high nutrient density in the seeds, cross-breeding for incorporating a desired trait within a plant, and genetic engineering to manipulate the nutrient content of the plant. In plant cross-breeding, all genes of the parent plants are combined and the progeny have both desirable and undesirable traits. To eliminate undesirable traits, plant breeders «back-cross» the new plant varieties with other plants over several generations. This technique, called hybridization, has been used to create varieties of low-phytate corn, barley, and rice. Using the techniques of genetic engineering, the gene(s) encoding for a desired trait(s) in a plant are introduced in a precise and controlled manner within a relatively short period of time. Golden rice, containing carotenoids, and rice with higher amounts of iron, are two examples of genetically engineered plants for improved nutrition. Genetic engineering has tremendous potential for revolutionizing nutrition. However, public concerns regarding safety, appearance, and ethics must be overcome before these products can be effectively introduced into the food supply.

Abstract:
Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to raise fertility and control weeds, pests and diseases. An alternative method promoted for exploring the value of variation and evolutionary fitness in crops is to create composite cross populations. Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins, recombination of these stocks by hybridization, the bulking of F1 progeny, and subsequent natural selection for mass sorting of the progeny in successive natural cropping environments. Composite cross populations can provide dynamic gene pools, which in turn provide a means of conserving germplasm resources: they can also allow selection of heterogeneous crop varieties. The value of composite cross populations in achieving these aims is dependent on the outcome of mass trials by artificial and natural selection acting upon the heterogeneous mixture. There is evidence to suggest that composite cross populations may be an efficient way of providing heterogeneous crops and of selecting superior pure lines for low input systems characterized by unpredictable stress conditions.

Abstract:
The rapid identification of sex in the dioecious hop (Humulus lupulus) is important for the breeding of this cultivated plant because only unfertilized flowers of the female plants are used as an ingredient in the production of beer. It is thought that a sex-chromosome mechanism controls the development of male or female plants. We have compared pools of male and female plants derived from a hop cross to identify molecular markers associated with the Y or male-specific chromosome. Of 900 functional RAPD primers, 32 revealed fragments specific for male plants that were absent in female plants of this cross. Subsequently, the 32 positive primers were tested on unrelated male and female plants. Three of these 32 primers were specific for the Y chromosome in all lines. The Y-specific product derived from one of these primers (OPJ9) was of low copy in hybridization experiments and predominantly present in male plants. Primers developed from the DNA sequence of this product provide a marker for rapid sex identification in crosses of hop by means of PCR.Key words: chromosomes, RAPD, sex-specific DNA sequences, plant breeding, Y chromosome.

Abstract:
A Multi-parent Advanced Generation Intercross (MAGIC) tomato population was developed by crossing eight founder lines chosen to include a wide range of variability. The lines were previously genotyped by a genotyping by sequencing approach. The MAGIC population was used to develop genotypes with important agronomic traits and to perform the Participatory Plant Breeding (PPB). Among the 400 plants of generation 4 (G4) of the MAGIC population cultivated in an organic field experiment, 22 individuals were phenotypically selected and a molecular analysis was done for both presence of resistance genes and fruit shape (marker assisted selection) on G5 seedlings. Three selected plants showed both the pyramiding gene of resistance to the main diseases and the ovate gene for pear shape typology. The 400 G10 stable lines that obtained from single seed descent will represent an important genetic resource for the tomato scientific community. The MAGIC population G4 was also cultivated in three organic farms located in North, Central and South Italy to carry out the PPB. The plants showed significant phenotypic differences in development, productivity and fruit color. This variability was used to select families of tomato adapted to low input crop management, different environments, agricultural practices and market conditions.

Abstract:
Abstract Uniparental genome elimination (UGE) refers to the preferential exclusion of one set of the parental chromosome complement during embryogenesis following successful fertilization, giving rise to uniparental haploid progeny. This artificially induced phenomenon was documented as one of the consequences of distant (wide) hybridization in plants. Ten decades since its discovery, attempts to unravel the molecular mechanism behind this process remained elusive due to a lack of genetic tools and genomic resources in the species exhibiting UGE. Hence, its successful adoption in agronomic crops for in planta (in vivo) haploid production remains implausible. Recently, Arabidopsis thaliana has emerged as a model system to unravel the molecular basis of UGE. It is now possible to simulate the genetic consequences of distant crosses in an A. thaliana intraspecific cross by a simple modification of centromeres, via the manipulation of the centromere-specific histone H3 variant gene, CENH3. Thus, the experimental advantages conferred by A. thaliana have been used to elucidate and exploit the benefits of UGE in crop breeding. In this review, we discuss developments and prospects of CENH3 gene-mediated UGE and other in planta haploid induction strategies to illustrate its potential in expediting plant breeding and genetics in A. thaliana and other model plants.

Abstract:
A mamona é uma cultura importante no nordeste brasileiro há muito tempo e é característica de pequenos produtores que utilizam mão de obra familiar. Devido a isso, a maioria deles não utiliza ainda cultivares melhorados e até o momento poucos cultivares de mamona foram liberados pelos programas de melhoramento. Nos últimos anos a cultura da mamona tornou-se importante também em outras regiões do Brasil, devido à importância que adquiriu o óleo extraído das suas sementes para a produção de biodiesel. O objetivo deste trabalho compreende a estimação de parâmetros genéticos e fenotípicos relacionados à produção e caracteres agronômicos de mamona, visando ao entendimento do controle genético de tais caracteres para fins de melhoramento. Para isso utilizou-se 10 genótipos de mamona, divididos em dois grupos: Grupo 1, composto de cinco genótipos de porte baixo, e, Grupo 2, composto de cinco genótipos de porte alto, que foram cruzados segundo um arranjo dialélico parcial, originando 25 cruzamentos. Os 25 tratamentos foram avaliados experimentalmente no ano agrícola de 2005/6 na área experimental do Departamento de Genética da ESALQ/USP, em um delineamento em látice 5 x 5 com quatro repetições e parcelas lineares de 9 metros, espaçadas de 3 metros, contendo 10 plantas. Os seguintes caracteres foram avaliados: produção de sementes (PR), peso de 100 sementes (P100), dias para florescimento (DF), altura da planta (AP), altura do caule (AC), diâmetro do caule (DC), comprimento total do racemo primário (TT), comprimento efetivo do racemo primário (TU), número de nós (NN) e comprimento dos internós (CI). A capacidade geral de combinação (CGC) foi significativa para todos os caracteres dos dois grupos na análise de variância, enquanto que a capacidade específica de combinação (CEC) foi significativa somente para P100, DF, DC, TT, TU e NN. Mesmo assim, a soma de quadrados devido à CGC foi maior que a soma de quadrados devido à CEC em todos estes caracteres. Nos dois grupos detectaram-se genótipos com alelos favoráveis para produção de sementes e caracteres agronômicos. Dois genótipos do Grupo 1 (BRA-5916 e BRA-3908) e dois do Grupo 2 (BRS Paraguaçu e BRS Nordestina) se destacaram pela maior concentração de alelos favoráveis para PR e características agronômicas, havendo complementação entre eles. Com base nestes resultados sugere-se a formação de populações derivadas de cruzamentos duplos, triplos e quádruplos com estes genótipos, visando à seleção de linhagens de alta produção e com características agronômicas favoráveis.
Castor has been a very important crop in northeastern Brazil, and has been characterized as low input agriculture of small farmers. Nowadays it became a very important crop in other places of Brazil, due to the possibility of biodiesel production. Most of castor crop in Brazil is based in landraces and only a few cultivars were released by breeding programs. The objective of the present work was to estimate the genetic and phenotypic parameters related to seed yield and agronomic traits in castor, in order to obtain a better understanding of the genetic control of these traits for breeding purposes. The genetic material comprised two sets of cultivars: Group 1, composed by five short genotypes, and Group 2, composed by five tall genotypes. The two groups were crossed according a partial diallel design, giving rise to 25 hybrid combinations. The 25 entries were evaluated under field conditions in the 2005/6 growing season, at Department of Genetics Experimental Station, College of Agriculture Luiz de Queiroz (ESALQ/USP) in a 5 x 5 lattice design with four replicates. Plots consisted of a 9-meter single row spaced 3 meter apart with 10 plants. The following traits were evaluated: seed yield (PR), 100-seed weight (P100), days to flowering (DF), plant height (AP), height up to primary raceme (AC), diameter of main stem (DC), total length of primary raceme (TT), effective length of primary raceme (TU), number of nodes up to primary raceme (NN) and length of internodes below the primary raceme (CI). General combining ability (GCA) was significant in the analysis of variance for all the traits in the two groups, while specific combining ability (SCA) was significant only for P100, DF, DC, TT, TU and NN. However, GCA sum of squares was higher than SCA sum of squares for all these traits. Both groups showed the presence of genotypes with favorable alleles for yield and agronomic traits. Two genotypes from Group 1 (BRA-5916 and BRA-3908) and two from Group 2 (BRS Paraguaçu and BRS Nordestina) presented a higher concentration of favorable alleles for PR and agronomic traits and were also complementary. We suggest the development of two-way, three-way and four-way populations with these genotypes, in order to select high yielding inbred lines and with other favorable traits.

Abstract:
A utilização de variedades resistentes é uma importante ferramenta no manejo integrado de pragas e vem sendo valorizada nos programas de melhoramento de plaritas. Neste estudo foram avaliados 12 genátipas de milho, em relação aos danos causados por Spodoptera frugiperda (J.E. Smith, 179r7) em condições de campo, e em relação ao efeito desses genófípos na biologia da praga, em condições de laboratório. Os experimentos de campo foram realizados nos municípios de Casa Branca, Florínea e Miguetópotis/Guaíra, representando três diferentes regiões do Estado de São Pauto. As plantas foram avaliadas nas idades de 6 a 8 e de 10 a 12 folhas, através de uma escala de notas de O a 9. Os resultados da anáfíse de varíãncía mostraram que os danos causados pela lagarta-do-cartucho nos genótipos de milho foram diferentes nos três locais avaliados. A interação idade*local foi significativa, indicando que, dependendo do local avaliado, os danos foram diferentes em cada idade. Na idade de 6 a 8 folhas, os danos foram significativamente menores em Casa Branca em relação à Florínea e à Miguelápolis/Guaíra. Na idade de 10 a 12 folhas, os três locais apresentaram danos significativamente distintos. Miguelápolis/Guaíra foi o local que apresentou menos -úanos, em relação à r'lorínea. Casa Branca foi o local em que ocorreu mais danos. Na comparação das médias entre as idades em cada local, Casa Branca apresentou os menores danos na idade de 6 a 8 folhas, enquanto que, em Florinea e iviiguetópolis/Guaíra, isso ocorreu na idade de 10 a 12 folhas. Corri base na analise -úe agrupamento para os experimentos de campo, os genótipos Z 8486, C 333 B e Diria 766 formaram o grupo daqueles menos danificados, enquanto que os genótipos XL 212 e Piranão formaram o grupo dos mais danificados peia iagarta-do-cartucho. Houve pouco efeito dos genótipos avaliados sobre a biologia do inseto. Nos experimentos de laboratório, os genótipos Z 8486 e Master proporcionaram menor peso de lagartas aos 7 e 14 dias, em relação aos genótipo XL 212, enquanto em Z 8486 e IAC-Vitória ocorreu menor viabilidade larval em relação à Dina 766. O genótipo Dina 766, que ficou entre os menos danificados em condições de campo, proporcionou maior peso larval aos 7 dias e maior viabilidade larval.
Plant resistance is a usefui component of integrated pest management and its value has been increasing in plant breeding programs, ln this study, 12 maize genotypes were evaluated to damage of fali armyworm Spodoptera frugíperda (J.E. Smith, 1797) in field conditions. The effect of these genotypes on fali armyworm biology was evaluated in laboratory conditions. The field experiments were carried out in Casa Branca, Florínea and Miguelópolis/Guaíra, whích represent three different regions of São Paulo State. The plants were evaluated at 6-8 and 10-12 exposed leaves, using a rank scale from O to 9. The analysis of variance showed that the fali armyworm damage on maize genotypes differed in each of three places. The interaction age*piace was significant and it indicares that the damage differed according to the age of the plants, depending on where they were evaluated. At 6-8 leaf stage, the damage were less significant in Casa Branca comparing to Florínea and Miguetópolis/Guaíra. At 10-1 2 leaf stage, the three places showed damage with significant differences. Migueiópolis/Guaíra was the place with fewer damage, comparing to Florínea. ln Casa Branca occurred more damage. Comparing the age average of the plants in each region, the plants in Casa Branca showed fewer damage at 6-8 leaf stage whereas the plants in Florinea and Miguelópolis/Guaíra showed it at 10-12 leaf stage. ln the field experiments, the Cluster Analysis showed that Z 8486, C 333 B and Dina 766 genotypes set the group wíth fewer fali armyworm damage whereas XL 212 and Piranão genotypes set the most damaged group. The genotypes provided littie effect on fali armyworm biology. ln the laboratory experíments, the larvae reared on Z 8486 and Master genotypes provided lower weight on days 7 and 14, when compadng to XL 212. The genotypes Z 8486 and IAC-Vitória presented lower larval survival when comparing to Dina 766. The larvae reared on Dina 766 genotype provided the highest weight for day 7 and the greatest larval survival, even though, this genotype was one of the least damaged in the field.

Full text
Abstract:
Leaf rust and stripe rust of wheat (Triticum aestivum L.) are caused by the fungal pathogens Puccinia triticina, and Puccinia striiformis f.sp. tritici, respectively. In North America, the incorporation of adult-plant resistance (APR) genes into breeding lines has been an important strategy to achieve durable resistance to both diseases. Previously, the spring wheat cultivar AC Domain was reported to express an effective level of adult-plant resistance (APR) to leaf rust under field conditions. Early gene postulation work had suggested AC Domain might carry the APR gene Lr34 due to its phenotypic similarity to other Lr34 carrying lines. However, new gene specific markers have shown that AC Domain is not a carrier of Lr34. The objective of this research was to genetically localize the resistance in AC Domain, which is important because the cultivar has frequently been used as a parent in Canadian breeding programs, primarily for its value as a source of pre-harvest sprouting resistance. A mapping population of 185 doubled haploid (DH) lines derived from the cross ‘RL4452’ by ‘AC Domain’ was used for this study. RL4452 is a known carrier of Lr34. During 2011-2012, the DH population was evaluated in field leaf rust nurseries at Saskatoon, SK and Portage, MB and at a stripe rust nursery at Lethbridge, AB. Field results indicated that rust resistance in the mapping population was variable, with lines ranging from highly resistant, to highly susceptible. DH lines carrying Lr34 showed a high level of resistance to both diseases. Thus, the non-Lr34 carriers were genotyped using select SSR markers, and by an Illumina 9k Infinium iSelect SNP assay for subsequent quantitative trait loci (QTL) analysis. QTL analysis revealed that AC Domain donated a major resistance QTL located on chromosome 2BS, that mapped 46 cM proximal to markers linked to Lr16, and explained a significant portion of the leaf and stripe rust phenotypic variance in all test environments. In addition, this QTL was significantly associated with the expression leaf tip necrosis (LTN), reduction in area under the disease progress curve (AUDPC), and coefficient of infection (CI). In certain environments the interaction between the 2B QTL and Lr34 was additive resulting in a superior level of rust resistance. Indoor rust testing showed AC Domain was susceptible to both diseases at the seedling stage. Taken together these results suggest that the identified resistance in AC Domain is likely due to the presence of an APR gene, on chromosome 2BS.

Abstract:
AbstractGenomic prediction and selection models (GS) were deployed as part of DataBio project infrastructure and solutions. The work addressed end-user requirements, i.e., the need for cost-effectiveness of the implemented technologies, simplified breeding schemes, and shortening the time to cultivar development by selecting for genetic merit. Our solutions applied genomic modelling in order to sustainably improve productivity and profits. GS models were implemented in sorghum crop for several breeding scenarios. We fitted the best linear unbiased predictions data using Bayesian ridge regression, genomic best linear unbiased predictions, Bayesian least absolute shrinkage and selection operator, and BayesB algorithms. The performance of the models was evaluated using Monte Carlo cross-validation with 70% and 30%, respectively, as training and validation sets. Our results show that genomic models perform comparably with traditional methods under single environments. Under multiple environments, predicting non-field evaluated lines benefits from borrowing information from lines that were evaluated in other environments. Accounting for environmental noise and other factors, also this model gave comparable accuracy with traditional methods, but higher compared to the single environment model. The GS accuracy was comparable in genomic selection index, aboveground dry biomass yield and plant height, while it was lower for the dry mass fraction of the fresh weight. The genomic selection model performances obtained in our pilots are high enough to sustain sorghum breeding for several traits including antioxidants production and allow important genetic gains per unit of time and cost.

Abstract:
Breeding of plutonium with light water cooling has been studied for many years, but high breeding to meet growing demand for electricity in a developed country has not been accomplished. The purpose of this study is to investigate a high breeding core of Super FBR (supercritical pressure light water cooled fast breeder reactor) with new fuel assemblies consisting of tightly packed fuel rods without gaps, which leads to low coolant to fuel volume fraction. The plant system of a Super FBR is once-through coolant cycle with high head pumps. The coolant flow rate is low due to the high enthalpy rise in the core. It is compatible with the high pressure drop of the new fuel assemblies. Both neutronic and thermal hydraulic design of the core is considered. The challenge of high breeding with light water cooling is to satisfy negative coolant void reactivity, high breeding and low enrichment simultaneously. The core with new assemblies has been designed with the average coolant density of 248 kg/m3. It is achieved by setting 380C inlet and 500C outlet temperature. For satisfying negative void reactivity, a solid moderator layer composed of zirconium hydride (ZrH) rods are adopted in some blanket assemblies. Cross sections of the blanket fuel assemblies with ZrH rods are prepared with assembly-wise calculation, because the pin-wise collision probability calculation overestimates the breeding. MOX fuel is used for seed fuel assemblies. Three types of core layouts with “radially heterogeneous”, “radiating” and “scattered” seed assemblies have been considered, and “radiating” layout shows best breeding characteristics among them. The seed assemblies in a “radiating” layout are not radially separated so that more numbers of blanket assemblies can be placed in high neutron flux region of a core. Fraction of blanket fuel assemblies with ZrH rods is selected for high breeding. Super FBR using the new fuel assemblies achieved both negative void and high plutonium breeding.

Abstract:
In a world striving for continuous improvement, the utility and manufacturing industries appear to have taken different paths to success. But are they the same and can we learn from them to take a revolutionary step towards manufacturing excellence for Westinghouse Nuclear Fuel? The safety critical environment that is the hallmark of the nuclear industry has led the Institute of Nuclear Power Operations (INPO) to develop a rigorous and disciplined approach to equipment reliability that is repeated across the nuclear generation industry. This is manifested in well documented processes and procedures in response to the heavily audited power generation segment. INPO’s Equipment Reliability guideline, AP-913, is a top down methodology that captures equipment history and best practices to tie together activities throughout a station to improve reliability. Manufacturing however is breeding a culture of continuous improvement, or “kaizens”, where “Lean” and “Total Productive Maintenance” (TPM) tools and techniques drive a multiplicity of incremental improvements. The manufacturing concepts and approaches of Lean and TPM were developed originally in Japan by such companies as Toyota and Motorola and formalized by the Japan Institute of Plant Management as an equipment management strategy, which was designed to support the Total Quality Management strategy. Lean and TPM are fostered by professional societies and are well described in a body of literature with decades of experience. Since this paper provides a cross-discipline comparison in a primarily nuclear applications conference, introductory material for the TPM methodology is referenced, while only overview concepts are described herein. It is hoped that this will spur the reader to develop a more complete understanding of TPM, to further integrate these applications in both industries. This paper provides an initial overview of how Westinghouse Fuel Manufacturing is developing an equipment reliability programme that is exploiting the best practices of the AP-913 integrated processes with the strong continuous improvement tool set of manufacturing. We have just begun to roll-out the new processes and guidelines. In future papers, more detailed comparisons and lessons learned from implementation will be described.
