籼稻稻米直链淀粉含量的胚、胚乳、细胞质和母体遗传效应分析

采用禾谷类作物种子数量性状遗传模型和统计分析方法， 分析了籼稻稻米直链淀粉含量的 胚、 胚乳、 细胞质和母体植株遗传效应以及环境互作效应。 结果发现稻米直链淀粉含量 的表现主要受制于基因的遗传主效应， 环境互作效应对其影响较小。 控制直链淀粉含量的 遗传主效应以胚乳效应为主， 细胞质效应和母体效应对直链淀粉含

Analysis of Embryo, Endosperm, Cytoplasmic and Maternal Effects for Amylose Content Trait in Indica Rice

Analysis of embryo, endosperm, cytoplasmic and maternal effects and environment interaction effects for amylose content(AC) trait in indica rice( Oryza sat iva L.) was conducted by using a full genetic model for quantitative traits of seeds in cereal crops. It was indicated by the results that the genetic main ef fects for AC trait were more important than the environment interaction effects. The main effect was endosperm effect in genetic main effects, but the cytoplasm ic and maternal effects could also significantly affect the performance of AC tr ait in indica rice. In the environment interaction effects, embryo genetic b y environment interaction effect was more important. This result showed that emb ryo genes could affect the AC trait, but the expression of genes could be easil y influenced by environments. The common narrow heritability and narrow interact ion heritability of AC trait were 33.50% and 16.16%, respectively. Predicted gen etic effects for parents indicated that 26715 and 1391 were better than other pa rents for improving the AC trait of rice.
