对中国各地的３２３７份食用豆类（绿豆Ｐｈａｓｅｏｌｕｓｒａｄｉａｔｕｓ，豇豆Ｖｉｇｎａｕｎｇｕｉｃｕｌａｔａ，豌豆ｐｉｓｕｍｓａｔｉｖｕｍ，菜豆ｐｈ．ｖｕｌｇａｒｉｓ和红小豆ｐｈ．ｃａｌｃａｒａｔｕｓ）种质资源进行了抗旱性鉴定。利用甘肃省敦煌市的自然干旱条件，以株高、单株荚数、于粒产量３个性状的抗旱指数作为综合评定抗旱性指标。鉴定出１级抗旱（高抗）资源１６０份，２级抗旱资源３７６份。初步研究表明：食用豆种内及种间抗旱性存在显著差异，种间抗旱性强弱顺序为：绿豆＞豇豆＞碗豆＞菜豆＞红小豆。抗旱性资源主要分布在长江以北地区，以山东、河北、内蒙古居多。
Drought resistance identification was conducted on the germplasm resources of 3237 food legumes in China (Phaseolus radiatus, Vignaunguiculata, pisumsativum, ph.vulgaris and ph.calcaratus). Based on the natural drought conditions in Dunhuang City, Gansu Province, drought resistance index of three traits including plant height, pod number per plant and grain yield was used as a comprehensive index to evaluate drought resistance. Identified a drought-resistant (high resistance) resources 160, 376 drought-resistant resources. Preliminary studies have shown that: there are significant differences in the drought resistance of legumes and between species, the order of drought resistance is: mung bean> cowpea> pea> pea> bean. Drought resistance resources are mainly distributed in the north of the Yangtze River, Shandong, Hebei, Inner Mongolia are mostly.
