Field reaction of 25 red mottled bean ( Phaseolus vulgaris L.) genotypes to common bacterial blight [Xanthomonas campestris pv. phaseoli (Smith) Dye] was evaluated in Puerto Rico over 2 years. The average disease severity (percent leaf area with symptoms) was similar over years. The determinate red mottled genotypes had almost twice as much disease as indeterminate genotypes. Eight of the indet...

introduction common bean (phaseolus vulgaris l.) is the world’s most important food legume. this staple is considered as a nearly perfect food mainly because of its high protein content and abundant fiber, complex carbohydrates, and other daily food needs such as vitamins (folate) and minerals (cu, ca, fe, mg, mn, zn). annual production, including both dry and snap bean, exceeds 21 million metr...

in this study the effect of salt stress on banding patterns of superoxide dismutase (sod), catalase (cat) and peroxidase (pox) in 18 genotypes of white common bean (phaseolus vulgaris l.) were examined under two levels of nacl )0 and 400 mm) stress. for each isozymic band the “density × area” scores on gels were evaluated by mcid software and considered as enzymatic activity. three isozymes wer...

to study the phenotypic and genotypic diversity of some important agronomic traits associated with yield in white beans, 30 genotypes of white bean were evaluated using a randomized complete block design with four replications in two environments under water stress and non stress conditions. analysis of variance for most of the traits showed significant differences among genotypes, indicating t...

fungal diseases, chocolate spot (botrytis fabae sard) is the most destructive diseases of faba bean and causes considerable dramatic damage losses on faba bean yield worldwide. the levels of resistance to chocolate spot were evaluated in 35 faba bean cultivars and one susceptible check (ilb365) and local check (barkat) at the gorgan agricultural research station during the 2010 and 2011 croppin...

Frost stress is one of the abiotic stresses that causes a significant reduction in winter faba bean yield in Europe. The main objective of this work is to genetically improve frost tolerance in winter faba bean by identifying and validating QTL associated with frost tolerance to be used in marker-assisted selection (MAS). Two different genetic backgrounds were used: a biparental population (BPP...
