摘　　要：为了探讨野生大豆抗旱性,发掘野生大豆抗旱种质资源,提高野生大豆抗旱种质资源的利用价值,需要合理鉴定与评价其抗旱性。在对400份野生大豆种质资源作了预备试验的基础上,选用20份野生大豆抗旱种质资源,通过成熟期的农艺性状综合表现和抗旱系数分析其抗旱性,发现野生大豆抗旱种质资源在不同生育期的抗旱性具有多样性,有些材料表现为全生育期抗旱,有些材料只在某个或几个生育期表现抗旱。同时,发现有些材料抗旱系数虽较小,但在对照条件下农艺性状表现好。In order to discuss the drought resistance of wild soybean and discover useful wild soybeans, it is required to scientifically identify and evaluate them. On the basis of pre-test for 400 wild soybeans, twenty wild soybean germplasms with drought resistance were analyzed in field drought condition. The results showed that there was diversity in drought resistance at different development stages. Some materials showed resistant drought in whole growing period, but the others just at one stage or several stages. It was also found that some materials showed good characters under irrigation.
