摘要
为给油茶定向育种提供理论依据,运用灰色关联度分析法对32个油茶杂交组合进行综合评判,分析了各品种的综合表现及各性状的作用关系。结果表明,各油茶杂交组合的加权关联度大小顺序依次为:XLH58,XLH63,XLH66,XLH68,XLH64,XLH76,XLH53,XLH65,XLH82,XLH77,XLH72,XLH79,XLH70,XLH57,XLH81,XLH80,XLH69,XLH75,XLH54,XLH78,XLH55,XLH51,XLH71,XLH59,XLH74,XLH61,XLH56,XLH73,XLH67,XLH60,XLH52,XLH62。各经济性状与产油量关系密切程度的顺序依次为:干籽含油率,鲜果出籽率,抗病性,果形指数,冠幅面积,总叶片数,单果质量,单株产果量。
In order to provide a theoretical basis for directional breeding,comprehensive evaluation of 32 hybridized combinations in Camellia oleifera was carried out by grey relational degree analysis,and relationship between comprehensive performance and every characteristics was overall analyzed.The results showed that the order of weighted relational degrees of hybridized combinations from high to low was XLH58,XLH63,XLH66,XLH68,XLH64,XLH76,XLH53,XLH65,XLH82,XLH77,XLH72,XLH79,XLH70,XLH57,XLH81,XLH80,XLH69,XLH75,XLH54,XLH78,XLH55,XLH51,XLH71,XLH59,XLH74,XLH61,XLH56,XLH73,XLH67,XLH60,XLH52 and XLH62 in turn.The sequence of affinity degree on oil yield was oil content of dry seeds, seed-producing ratio of fresh fruit,disease resistance,index of fruit shape, crown area,total quantity of leaves,mass per fruit and output of fruit per tree from high to low.
