SCREENING OF EXOTIC DRY BEAN DROUGHT TOLERANT GERMPLASM IN WESTERN NEBRASKA

摘要

Intermittent water stress is the single most important abiotic stress affecting yield and seed quality of dry beans. Declining ground water and diminished surface water supplies during drought are not new problems for dry bean production areas, however, the drought across the inter-mountain west and Great Plains over the past six years has magnified yield losses. Water allocations are already in place in several Nebraska, Kansas and Colorado areas for both ground and surface water. The objective of this research was to screen and identify elite exotic dry bean germplasm for drought tolerance.
