近年来,数量遗传学者提出了可预测作物杂种后代在多环境中的基因型值和遗传效应的新方法,并已在水稻、棉花等作物上广泛应用,这为深入揭示基因型×环境互作的生物学本质,阐明多环境下数量性状的遗传表现规律提供了有效方法。本文旨在应用包括基因型×环境互作效应的加性-显性遗传模型和统计方法,分析水稻籼粳杂交不同衍生世代材料的产量相关性状在两个不同地点的表型值和遗传效应的变化
In recent years, quantitative geneticists have proposed new methods for predicting the genotype value and genetic effect of crop hybrid offspring in multiple environments and have been widely used in rice, cotton and other crops. This is a good way to reveal the interaction between genotype × environment The biological nature of the quantitative elucidation of quantitative traits in the genetic performance of the law provides an effective method. The purpose of this paper is to analyze the phenotypic values and genetic effects of yield-related traits in two different generations of indica-japonica hybrid rice by using additive-dominance genetic models including genotype × environment interaction effects and statistical methods Variety
