对３０份小麦品种（系）孕穗期有关性状湿害指数间的相关及通径分析表明：过湿主要导致主穗粒数锐减、千粒重下降，其遗传效应与环境作用并存；以湿害指数为基础，以抽穗后１５ｄ的主茎绿叶数为初测指标，结合考察籽粒产量综合评价基因型间的耐湿性差异的方法是切实可行的。品种耐湿性的遗传特性为筛选综合性状较好且耐渍的新品种提供了理论依据。 Correlation and path analysis of the wetting index of the related traits at the booting stage of 30 wheat cultivars (lines) showed that: the over-wetting resulted in the sharp decrease of main grain number and the decrease of 1000-grain weight, the coexistence of genetic effect and environmental effect; As the basis, taking the number of green leaves of main stem 15 days after heading as the initial test index, combined with the study of grain yield comprehensive evaluation of the differences in moisture resistance between genotypes is feasible. The genetic character of the moisture tolerance of cultivars provides a theoretical basis for screening new varieties with better comprehensive characters and resistance to stains.
