dominance variance

Conditional analysis showed that conditional additive and dominance variance performed fluctuation at different developmental periods . The results indicated that the genes controlling plant height expressed discontinuously and unstably .

在条件方差分析中，条件加性方差和条件显性方差均表现出一定的波动性，表明控制株高性状的基因在整个发育时期并非持续、稳定表达。

Additive variance was higher than dominance variance , which indicates quantitative inheritance .

加性的变异高于显性的变异，表明是数量遗传。

The phytate content in rice grain had significant variance of genotype , which was controlled by genetic system of maternal plant and seed , which among them , seed direct dominance variance is the most important effect , next is maternal dominance effect and maternal additive effect .

水稻植酸含量存在显著的基因型差异，受母体植株及种子中遗传体系的共同控制，其中种子直接显性遗传效应占主导地位，其次是母体显性和加性效应。

The ratio of sum of additive effect variance to total genetic variance were 18.8 % , and that of sum of dominance effect variance to total genetic variance were 81.2 % .

在胚和母体两套遗传体系中，加性效应方差占总遗传方差的18.8%，胚显性方差与母体显性方差之和占总遗传方差的81.2%。
