摘　　要：通过分析干旱胁迫灌水与浅水灌溉对照处理条件下水稻生育期、农艺性状及产量性状的变化,探讨了20份水稻种质资源的耐旱性。结果表明:干旱胁迫处理条件下水稻生育期延长,农艺性状及产量因子水平均低于对照处理条件下水平。从抗旱指数与理论产量综合评价,垦01-1387、垦稻12、绥粳3、松粳4、北稻4等品种(系)的抗旱能力相对较强。Drought resistance of 20 rice stable varieties was studied by change of the agronomic characters of rice varieties growth period and yield,in drought stress irrigation and contrast of rice processing conditions,the results showed that under the condition of drought stress processing extension,rice growth and yield of agronomic characters are factor leels than controls processing conditions level.From drought resistance index and theoretical yield and comprehensive assessment,Ken 01-1387,Kendao 12,Suijing 3,Songjing 4,Beidao 4 several varieties（strains） have a strong ability of drought resistance.
