在不同土壤水分条件下对耐旱小麦品种(系)的产量及其它农艺性状进行研究，结果表明，在干旱条件下，小麦产量与单株穗数、单株粒重、株高均呈极显著正相关，其相关系数分别为0．7955，0．5383和0．4977，而与千粒重和穗粒重呈极显著负相关，其相关系数分别为-0．5423和-0．4570。因此，在耐旱品种选育过程中，以选择单株穗数多、成穗率高的材料为宜。另外，根据耐旱性和产量表现，对试验材料进行分类。

The yield and agrinomic traits of drought enduring wheat varieties was studied under various water condition. The results showed that, in drought condition, wheat yield was highly significantly correlated with ear number per plant, grain weight per plant and plant height, the correlation coefficients were 0. 7955, 0. 5383 and 0. 4887 respectively. But wheat yield was negatively correlated with 1000 grain weight and kernel weight per ear, the correlation coefficienes were-0. 5423 and-0. 4570respectively, So during selecting for drought enduring wheat varieties, We should pay attention to ear number per plant.
