摘　　要：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。This paper presents on the research resalts to canonical distance of millet.We studying correlation between genotupic and phenotypic variates of multiple quantitative traits with multivariate statistical analysis,and its canoni- cal distance were discused in this article.The first canonical character has the largest heritbility which is named the I'th canonical character.It can make a sufficient utilization of information in the test only to study a few canonical characters in pratical situations,and its possible uses in breeding of millet are discussed.
