摘　　要：把小麦各性状的耐湿系数作为衡量各单项耐湿能力大小的指标,用主成分分析将各单项耐湿系数综合成几个新的相互独立的综合指标,再利用隶属函数求出综合指标的隶属值.这样,通过各小麦品种(系)的隶属值可求出各品种(系)耐湿性度量值后,可以较准确地评价各小麦品种(系)的耐湿性.Use the waterlogging resistance coefficient of single character to value the single capacity of waterlogging resistance,and then synthesize it to some new independent, comrehensive indexes by using principal component analysis.On this base,we can get the subordinate value of comprehensive indexes by using subordinative function.So we can get the waterlogging resistance value of different wheat.Basing on the waterlogging resistance value we can evaluate waterlogging resistance of different wheat.
