本研究了小麦籽粒蛋白质合量在Fl及F2代中的表现情况。结果表明,控制蛋白质合量的基因作用以加性效应为主,同时存在非加性效应;Fl代子粒蛋白质合量与双亲平均值高度相关,F2代中子粒蛋白质合量分离呈正态分布,且正态分布的峰值蛋白质合量也接近双亲平均值。蛋白质合量的一般配合力大于特殊配合力方差,并计算了蛋白质合量的广义和狭义遗传力。
The expression of wheat grain protein content in F1 as well as descendant F2 were studied. The result showed that the genes that control protein content transmitted to the descendants were mainly based on additive effect, but also with the non-additive effect. The grain protein content of F1 was highly related to the average value of both parents,and the protein content in descendant F2 appeared in normal distribution. The variance of general combining ability is larger than that of special combining ability. The heritability in broad and narrow sense were calculated.
