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 ...
Identification of genes and genetic mechanisms contributing to heat tolerance. Sources of heat tolerance
Two temperature controlled greenhouses were used to conduct a trial at CIAT. A set of 192 genotypes including 101 accessions of P. vulgaris, 81 accessions of P. acutifolius and 10 accessions of P. parvifolius, were evaluated ...
Geographic priorities for research and development on dryland cereals and legumes
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 ...
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. ...
Identifying genes and QTL associated with heat tolerance. Genomic regions for heat tolerance identified in interspecific progeny
Initial results with GBS suggested that introgression had occurred across a wide part of the genome when a large number of lines were considered (Figure 1). GBS also suggested that heat tolerant line INB 841 had very ...

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 ...
Physiological traits associated with drought resistance in Andean and Mesoamerican genotypes of common bean (Phaseolus vulgaris L.)
Common bean (Phaseolus vulgaris L.) is the most important grain legume for human consumption, and drought stress affects over 60% of dry bean production worldwide. Field and rainout shelter studies were conducted at the ...
Achieving sustainable cultivation of grain legumes –Vol I. Advances in breeding and cultivation technique
“This reference will greatly improve the visibility of,
and access to knowledge about crops that play such a
critical role in sustainable cropping systems, nutrition
and income, yet which often remain under the radar ...
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 ...
