ANDEAN BEAN PERFORMANCE UNDER TERMINAL DROUGHT IN WASHINGTON

摘要

The effects of drought on common bean are dependent on the intensity, type, and duration of the stress (Munoz-Perea et al., 2006). In Africa, an estimated 682,000 hectares of beans are cultivated in semi-arid environments, with annual yield losses todrought of 781,000 tons across all environments (Wortmann et al., 1998). Highland Mexico, Central America, Northeast Brazil, and much of Eastern and Southern Africa are bean producing areas where drought is endemic. Using climate models the effect of global climate change is predicted to be more severe in the fiiture (Williams et al., 2007). Identification of dry beans that require less water or have better water use efficiency will enhance management options for maintaining profitability. Our objective was to screen lines from the Andean Diversity Panel (ADP) (Cichy et al., 2015) for reaction to terminal drought stress.
