PHENOTYPIC EVALUATION OF A SUBSET OF THE PHASEOLUS VULGARIS CORE COLLECTIONS, THE P. ACUTIFOLIUS GERMPLASM COLLECTION, AND CULTIVARS FOR DROUGHT TOLERANCE IN NEBRASKA AND PUERTO RICO

摘要

Drought stress is an important constraint to common bean production worldwide and is an increasing constraint on US production (Singh, 2007; Munoz-Perea et al., 2007). To address this issue, exotic common bean and tepary bean germplasm from the NPGS and CIAT collections and from US and international breeding programs were evaluated for their response to drought stress.
