Additive- and dominant-effect genes governed grain filling commonly and the fonner acted mainly with less variation range of total genetic effects in late season, compared to that in early season.
晚季加性和显性效应基因共同控制谷粒充实，但以加性效应为主，总遗传效应变化幅度较早季小。

As the hybrid generation advanced, the ratio of additivevariation to total genetic variation increasingly added.
随世代推进，基因加性变异在总遗传变异中的比重逐渐加大。

The variation made up in all of the traits was mostly inherited, and the additivegenetic correlations between each pair of the majority of traits studied were apparent.
