Root hair length evaluated
A field trial was conducted during the dry season (May to July 2016) at Darien, Valle del Cauca-Colombia, The BASE (Bean Abiotic Stress Evaluation). The BASE trial included 80 bean genotypes: 58 belong to Mesoamerican gene ...
Demand is quantified for common bean
This objective was completed ahead of schedule, but a summary is presented here. Data on production of pulses and human population suggest that per capita consumption must be declining. This raises critical questions among ...
Evidence for genotypic differences among elite lines of common bean in the ability to remobilize photosynthate to increase yield under drought
Common bean (Phaseolus vulgaris L.) is the most important food legume for human consumption. Drought stress is the major abiotic stress limitation of bean yields in smallholder farming systems worldwide. The current work ...
Sowing density effect on common bean leaf area development
Sowing density is a major management factor that affects growth and development of grain
crops by modifying the canopy light environment and interplant competition for water and
nutrients. While the effects of sowing ...
Phenotypic differences in adaptation to combined stress of inadequate P supply and drought (BASE 80 trial)
A field trial was conducted during the dry season (May to July 2016) at Darien, Valle del Cauca-Colombia, The BASE (Bean Abiotic Stress Evaluation). The BASE trial included 80 bean genotypes: 58 belong to Mesoamerican gene ...
Phenotypic evaluation of the effect of high temperatures (2°C and 4°C above ambient temperature) on elite common bean lines
A heat tolerant trial of Andean beans was planted in Alvarado (Tolima) (July to November 2016). A total of 157 individual selections were planted. A total of 8 F1.3 and 31 F1.4 were selected under conditions of heat stress. ...
Geographic priorities for research and development on dryland cereals and legumes (DCL)
Maps, geography and spatial
analysis are increasingly important
for developing R&D programs,
priority setting, monitoring,
impacts assessment and reporting.
• But the community of researchers
working on this topics has ...
Breeding lines with improved performance under P and water limitation. Improved lines for combined stress of drought and low P identified
Simple, 3-way and double (4 parent) crosses are created among stress tolerant parents, and including parents for high grain iron. F2 populations are screened under drought stress and promising families are harvested in ...
Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance
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 ...
