对水稻的一些与当前市场商品价值有关的品质性状(米粒长、宽、厚、粒重、腹白、脂肪含量)的遗传结构、遗传力与遗传传递动态进行研究。通过对3个籼稻优质品种分别与非优质品种杂交的杂种后代的分析,提出了上述性状表现为多基因累加效应的遗传,其中有的还有显性效应的作用;不少性状的遗传力较大。此外,对脂肪含量的遗传以及杂种中两代基因型对米质发生的影响等问题提出了讨论。
The genetic structure, heritability and genetic transmission dynamics of some rice quality traits (grain length, width, thickness, grain weight, belly white, fat content) related to the value of current market products were studied. Based on the analysis of the offspring of three elite hybrid indica hybrids with non-elite varieties, the inheritance of the above-mentioned traits as multi-gene additive effects was proposed. Some of them also had the dominant effect. The heritability of many traits Big. In addition, the discussion of the inheritance of fat content and the influence of genotypes of two generations on the occurrence of rice in hybrids were discussed.
