摘　　要：筛选豌豆苗期抗旱种质资源,对豌豆品种改良、促进豌豆产业发展具有重要意义。本研究以搜集内蒙地区的39份豌豆种质资源为材料,采用盆栽并对幼苗进行反复干旱处理。测定幼苗存活率、叶片萎蔫指数、株高、叶片鲜重、叶片干重、叶片含水量、生物量和植株干物质胁迫指数指标。采用隶属函数法综合评价豌豆种质资源耐旱等级,获得苗期抗旱材料27份、中抗种质资源11份和敏感种质资源1份。It is significant to identify and screen drought resistant germplasm resources at pea seedling stage for improving pea varieties improvement and development of pea industry. 39 accessions of pea resources were collected in Inner Mongolia were used as materials in this study. Pot experiment was conducted to measure survival rate of seedlings, wilt index, plant height, weight of fresh leaf, weight of dry leaf, relative water content, biomass weight and stress index by using the method of repeat drought stress at seedling stage. The various resistant accessions of pea germplasm re-sources screened by subordinative function analysis included 27 resistant, 11 moderately resistant and 1 susceptible.
