摘要
运用灰色系统理论和关联度分析法 ,对通辽地区 2 5个蓖麻杂交F1代 12个单株产量构成因素进行关联分析 .结果表明 ,蓖麻杂交种产量构成各因素灰色关联度大小依次为单株粒数 >一级分枝粒重 >一级分枝蒴果数 >门桩穗长 >生育期 >百粒重 >主茎穗长 >株高 >一级分枝果穗数 >主茎粒重 >主茎蒴果数 >主茎穗位 .与单株产量密切相关的性状为单株粒数、一级分枝粒重、一级分枝蒴果数。
The correlation of 12 yield components of 25 castor hybrids F 1 were studied by grey correlative degree analysis in this paper.The results showed that the yield per plant was closely related to seed number per plant,seeds weight of primary branches,number of capsules on primary branches,ear length of primary branchs and growing days.
