本文根据杨德等人提出的典范性状,相关遗传力的概念,并参考有关主成分分析方法及聚类方法的研究,首次分析了谷子的典范性状。典范性状是测量数量性状所有线性组合中具有最大遗传力的线性组合。在育种过程中,只须取少数典范性状进行研究就能得到较可靠的信息。本研究试图为谷子育种提供可靠的科学依据。 Based on the concept of canonical traits and related heritability proposed by Yang De et al., And referring to the research on principal component analysis and clustering methods, this paper analyzes for the first time the typical traits of millet. An exemplary trait is a linear combination with the greatest heritability of all linear combinations of quantitative traits. In the breeding process, only a small number of canonical traits can be studied to get more reliable information. This study attempts to provide reliable scientific basis for millet breeding.
