以籼、粳、爪不同类型水稻品种所配制的５个组合的６世代群体为试材，分析了蛋白质含量的基因效应及效应平方和。结果表明，蛋白质含量的遗传中，加性效应比显性效应重要，上位性效应也具有重要作用，而以加性与加性互作为主，加性类效应明显大于非加性类效应，亲本隐性基因较多。蛋白质含量的遗传改良可以累加选择 Six generations of five combinations of rice varieties with different types of indica, japonica and claw were used as materials to analyze the gene effect and square sum of effect of protein content. The results showed that the additive effect was more important than the dominant effect and the epistatic effect was also important in the inheritance of protein content. The additive effect was mainly additive and additive, and the additive effect was more obvious than the additive effect. More recessive genes. Genetic improvement of protein content can be additively selected
