| 摘 要： | 本文对不同地区谷子品种的12个数量性状进行了相关遗传力分析、典范性状分析、聚类分析和判别分析。77个谷子品种分为11类,不同类群都各具特色。谷子品种的遗传分歧和地理远缘具有一定的平行关系,选出穗粒重、码数、茎粗、草重、节数等5个性状,作为分类这些谷子品种的重要性状。研究表明,多元遗传分析用于谷子种质资源的数量分类上,有助于客观分类,在一定程度上能反映客观实际情况。

| Abstract: | Observed 12 characters of foxtail millet cultivars were analyzed by correlative heritability,canonical charac- ter,cluster and discriminant analytical methods.Seventy seven foxtail millet cultivars were grouped into 11 clus- ter groups.There was parallelism between genetic diversity and geographical distance.The 5 characters used for grouping included grain weight of ears,number of spikelets,stem thickness,straw weight and number of nodes. Use of multivariate genetic analysis in quanlitatively grouping foxtail millet germplasm resources can reflect the re- al situations. |
