1983年戴君惕等提出相关遗传力概念,近年来在春小麦、水稻数量性状的遗传分析中取得了较好的应用效果。应用相关遗传力分析方法,能将性状表型值、基因型值、遗传力和相关系数联系起来考虑,从而包括了通路的全部信息,使分析更全面有效。本研究用相关遗传力对20个新育成品种(系)进行分析,以确定直接、间接选择效果,为今后的育种实践提供参考。 In 1983, Dai Junti et al proposed the concept of heritability, and achieved good results in the genetic analysis of spring wheat and rice quantitative traits in recent years. Applying the related heritability analysis method, the phenotypic value, genotype value, heritability and correlation coefficient can be considered in order to include all the information of the pathway so that the analysis is more comprehensive and effective. In this study, 20 newly bred varieties (lines) were analyzed with relevant heritability to determine the direct and indirect selection effects and provide reference for future breeding practice.
