摘要
利用５ 个小麦亲本， 按 Ｇｒｉｆｆｉｎｇ 方法４ 组配一套完全双列杂交， 研究小麦籽粒蛋白质组分的配合力和遗传力。结果表明， 同一性状不同亲本的一般配合力效应和不同组合间的特殊配合力效应差异都较大。球蛋白、醇溶蛋白和谷蛋白含量的遗传主要受加性基因控制， 清蛋白含量的遗传不存在加性基因作用， 以显性基因作用为主。
A set of diallel crosses involving 5 wheat parents, according to the random model of Griffing Method 4, was made to study the combining ability and heritability of grain protein components in wheat The results indicated that GCA effects of different parents for the same trait varied significantly And SCA effects of different combination studied varied obviously The inheritance of globulin, gliadin and glutenin contents were mainly controlled by additive genes Dominant genes functioned mainly on albumin content without additive gene
