Traits and genotypes related with drought resistance in Mesoamerican and Andean gene pool in common beans. Results showed that five Mesoamerican lines SEA 5, SEA 15, SER 22, SER 16, SER 8 and one Andean line SEQ1003 have superior resistance to drought. The superior performance of these lines unde...

A new methodology to estimate phenotypic differences in SNF ability. We used 15N natural abundance method to compare SNF ability estimated from shoot tissue sampled at mid-pod filling growth stage vs. grain tissue sampled at harvest. We suggest that the method of estimating Ndfa using grain tissu...

Many Countries could experience unprecedented heat stress because of global climate change (Battisti and Naylor,2009). Heat sensitivity in common bean is a major limiting factor that can reduce yield, quality, and lead to restricted geographic adaptation (Beebeetal.,2011). Interspecific lines dev...

Water stress is one of the major abiotic stress limitations for grain legume production in smallholder agricultural systems. Phenotypic characterization of water consumption by different species of legumes and genotypes within them plays a key role in adaptation to drought. Dynamics of water use ...

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 ...

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 resista...
