productivity of the bean crop in the United States. Hoyos-Villegas et al. report 27 marker associations with traits controlling drought tolerance in common bean. These associations include seven mark- ers for shoot biomass at maturity on Phaseolus vulgaris (Pv) chromo- some Pv11, two markers for shoot biomass at flowering on Pv02 and Pv08, two markers for seed size on Pv09, seven markers for lodging score on Pv02 and Pv07, one marker for leaf elongation rate on Pv03, and one marker for wilting score on Pv11. Positional candi- date genes associated with wilting score identified on Pv11 were located in the exon region of the Pv SIP1;3 gene, which codes for an aquaporin associated with water movement in beans.
