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...

Heat tolerance in common bean derived from interspecific crosses
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 ...

Water use in bean and cowpea: efficiency or effective use of water?
Common bean productivity is reduced by several abiotic stress factors like drought and low soil fertility, leading to yield losses particularly in low input smallholder farming systems in the tropics.
To understand the genetics of stress tolerance, and to improve adaptation of common bean to adv...

QTL analyses for tolerance to abiotic stresses in a common bean (Phaseolus vulgaris L.) population
Common bean (Phaseolus vulgaris L.) is the most important food legume crop in Africa and Latin America where rainfall pattern is unpredictable. The objectives were to identify better yielding common bean lines with good canning quality under drought, and to identify traits that could be used as s...

Drought Resistance of Common Bean Water Spending and Water: Saving Plant Ideotypes
The common bean is a tropical facultative short day legume that is now grown in tropical and temperate zones. This observation underscores how domestication and modern breeding can change the adaptive phenology of a species. A key adaptive trait is the optimal timing of the transition from the ve...

A Predictive Model for Time-to-Flowering in the Common Bean Based on QTL and Environmental Variables
Crop yield requires leaf area to intercept solar radiation and to undertake photosynthesis, both of which depend on nitrogen (N) accumulation. Further, the amount of accumulated plant N at the beginning of seed fill serves as the reservoir for N required in synthesizing the proteins in developing...

Drought stress limits growth and yield of crops, particularly under smallholder production systems with minimal use of inputs and edaphic limitations such as nitrogen (N) deficiency. The development of genotypes adapted to these conditions through genetic improvement is an important strategy to a...
