Bean rust, caused by Uromyces appendiculatus, is a devastating disease of common bean (Phaseolus vulgaris) in the Americas and Africa. The historically important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen that overcome other rust resistance genes. Existing molecular markers tagging Ur-3 for use in marker-assisted selection produce false results. Here, w...

The development of common bean cultivars with high technological quality that are biofortified with minerals, is required to meet the demand for food with health benefits. The objectives of this study were to evaluate whether common bean genotypes differ in terms of technological and mineral biofortification traits, to study the correlations between these characters, to analyze the genetic diss...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

Shoot biomass is considered a relevant component for crop yield, but relationships between biological productivity and grain yield in legume crops are usually difficult to establish. Two field experiments were carried out to investigate the relationships between grain yield, biomass production and N and P accumulation at reproductive stages of common bean (Phaseolus vulgaris) cultivars. Nine an...

Faba beans are widely consumed in Egypt as a vegetable by many ways. A study was conducted to determine the levels of phenolic compounds and antioxidant properties of raw seeds, green seeds and sprouts of ten faba bean cultivars commonly consumed in Egypt. Nubaria 2, Sakha 2 and Nubaria 1 cultivars showed higher amounts of phenolic compounds and exhibited the highest antioxidant activities (DPP...

Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...

in order to study the biological fixation efficiency of different strains of symbiosis bacteria in three varieties of common bean (phaseolus vulgaris l.) a factorial experiment based on randomized complete block design was conducted in zanjan province during 2006 and 2007. in this investigation three strains of rizobium including: rb117 (extracted from the zanjan soils), rb123 (extracted from t...

Dissemination pathways of common bean (Phaseolus vulgaris) cultivars from their areas of domestication to other parts of the Americas were determined using phaseolin type, as determined by 1-dimensional SDS/PAGE. Common bean cultivars of lowland South America exhibited approximately equal numbers of 'S' and "T' phaseolin types. "S" cultivars of that region may have been introduced along a route...
