1979～1982年,选用籽粒蛋白质、赖氨酸与色氨酸含量不同的6个小麦品种,进行了完全双列杂交,分析了杂种优势与 F_1、F_2的一般配合力和特殊配合力。所有性状的实际优势的平均值均为负值;超亲优势的变幅:蛋白质(%)为-11.9～6.41%,赖氨酸(克/100克蛋白质)为-18.63～6.75%,色氨酸(克/100克蛋白质)为-16.71～9.10%。所有性状的一般配合力与特殊配合力方差均为高度显著,表明在本实验中基因的加性效应和非加性效应均起重要作用。但 GCA/SCA 值较大,表明前者是比较主要而稳定的。特殊配合力效应在两个世代间有变动,说明基因的非加性效应在世代间是不很稳定的。
From 1979 to 1982, six wheat cultivars with different contents of grain protein, lysine and tryptophan were used for complete diallel crossing. The general combining ability and the special combining ability of heterosis with F 1 and F 2 were analyzed. The average value of the actual advantages of all traits was negative. The transmutation of superparents was -11.9 ~ 6.41% for protein (-11.9 ~ 6.41%), -18.63-6.75% for lysine (g / 100g protein) Acid (g / 100 g protein) was -16.71 to 9.10%. The general combining ability and the special combining ability variance of all traits were highly significant, indicating that the additive and non-additive effects played an important role in this experiment. However, the larger GCA / SCA value indicates that the former is more stable than the other. The special combining ability effect changes between two generations, indicating that the non-additive effect of genes is not very stable between generations.
