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 ...

Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance
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...

Evidence for genotypic differences among elite lines of common bean in the ability to remobilize photosynthate to increase yield under drought
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...

Root traits and their potential links to plant ideotypes to improve drought resistance in common bean
Terminal drought is a worldwide constraint to common bean production and its negative effects will be increased by climate change. The objective of this research was to characterize phenotypically advanced lines and commercial cultivars of common bean for their resistance to terminal drought stre...

Se analizaron diferencias fenotípicas en el desarrollo y distribución de raíces en condiciones de sequía de 16 genotipos de fríjol común. Se desarrolló un método utilizando tubos plásticos transparentes insertados en otros de PVC, llenos de mezcla de suelo con arena (2:1, peso:peso), en condicion...

Interspecific lines obtained from crosses between common bean (Phaseolus vulgaris L.) and other species from its secondary gene pool have a tendency for excessive vegetative growth and low grain yield. Contrariwise, drought-adapted common bean lines have been observed to produce high yields despi...
