“More than 60% of common bean (Phaseolus vulgaris L.) production worldwide is impacted by the risk of drought. In this study, the goal was to evaluate 64 bush bean genotypes from the CIAT reference collection to identify possible sources of drought resistance in the Andean gene pool. Phenotypic traits such as yield, 100-seed weight (P100) and days to physiological maturity (Dpm) were evaluated on selected accessions of this collection which was grown in an 8x8 lattice with two repetitions under three environments: intermittent drought (SI) and irrigation (R) in Palmira as well as early drought (ST) in Darién, Colombia. The genotypes included 20 from the Nueva Granada 1 (NG1) sub-race, 19 from the Nueva Granada 2 (NG2) sub-race, 10 from race Peru (P), 14 Andean control genotypes and one Mesoamerican check. The variables were analyzed through a combined ANOVA across environments, while simple correlations between yield and others variables were determinate. The genotypes with better adaptation to drought showed higher yields, 100-seed weight and fewer days to physiological maturity.”
