Populations of Rhizobium leguminosarum biovar viciae were sampled from two bulk soils, rhizosphere, and nodules of host legumes, fava bean (Vicia faba) and pea (Pisum sativum) grown in the same soils. Additional populations nodulating peas, fava beans, and vetches (Vicia sativa) grown in other soils and fava bean-nodulating strains from various geographic sites were also analyzed. The rhizobia ...

Common bean ( L.) breeding programs aim to improve both agronomic and seed characteristics traits. However, the genetic architecture of the many traits that affect common bean production are not completely understood. Genome-wide association studies (GWAS) provide an experimental approach to identify genomic regions where important candidate genes are located. A panel of 280 modern bean genotyp...

Common beans are a warm-season, food legume cultivated in areas prone to water limitation throughout their growing season. This study assessed the magnitude and pattern of trait associations for a total of 202 common bean genotypes divided into panels of 81 Andean and 121 Mesoamerican gene pool accessions grown under contrasting treatments of well-watered, non-stress, and water-limited, termina...

Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to these conditions. Field studies were conducted at the International Center for Tropical Agriculture ...

Drought is the major abiotic stress factor limiting yield of common bean (Phaseolus vulgaris L.) in smallholder systems in Latin America and eastern and southern Africa; where it is a main source of protein in the daily diet. Identification of shoot and root traits associated with drought resistance contributes to improving the process of designing bean genotypes adapted to drought. Field and g...

Common bean (Phaseolus vulgaris L.) is the most important grain legume for direct human consumption worldwide and represents a rich source of protein, vitamins, minerals, and fiber (Broughton et al., 2003). The recent sequencing of the common bean genome, together with the availability of genomic and transcriptomic data have provided useful information to common bean breeders that will help in ...

Common bean (Phaseolus vulgar is L.) demand is increasing with an alarming rate around the world, especially in Latin America, Africa, and Asia. Therefore, increased bean yield per hectare i.s the best way to meet the world demand rather than expansion of area under cultivation. The objectives of this experiment were to determine the genotypic variations for green bean and dry seed yield and ma...

Fifty two genotypes of Indian bean were examined for the genetic variability parameters and trait correlation 11 yield contributing traits in F5 progenies. Analysis revealed that these had a considerable level diversity. The magnitude GCV PCV was high seed per plant, which indicated potential selection based enhancement. values moderate pod weight, pods width length. High heritability along wit...

in order to evaluate the effect of salicylic acid on yield and yield components of bean genotypes under water deficit stress, an experiment was carried out as a factorial split plot design with three replications in research farm bu ali-sina university (hamadan, iran) during 2009. stress levels: consist of vegetative water stress, reproduction water stress and without water stress (control) and...
