The results showed that length from flag leaf pulvinus to spike base has the largest coefficient of variance of 42.1% and 37.2% in both DS and WW environments, respectively, while the spikelet per spike has the smallest CV of 6.4% and 5.7%. Under different water regimes, spike number per plant, effective spikelet per spike and peduncle length contribute a lot to the stable grain yield. Genetic diversity indices of DTI were from 1.95 to 2.07, with an average value of 2.02. Based on the DTI of agronomic traits, all accessions could be clustered into seven groups, the first and third groups are not sensitive to the water regimes, and the second group is more suitable for planting in dryland.

结果表明：在雨养和灌溉条件下，穗叶距的变异系数最高，分别为42.1%和37.2%，单穗总小穗数的变异系数最低，为6.4%和5.7%；不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；性状耐旱指数的多样性指数在1.95到2.07之间变化，平均值为2.02；根据性状耐旱指数将供试材料分为7个类群，其中第I、第III类群材料表现为对水分条件不敏感，而第II类群材料更适于在干旱条件下种植。
