摘要：

为了更好的在今后的杂交育种实践中利用已有的高粱品系，此研究以120个高粱品系的5个主要农艺性状的田间调查数据的平均值作性状比较进行数据统计分析和聚类分析。结果表明：全生育期的变异系数较低，株高、主穗长的变异系数中等，千粒重、单穗粒重受环境影响的变异系数大，这两种性状可利用于杂交和选择育种；120个高粱品系可分为2大类，又可进一步划分为6大亚类，各亚类各有其特点，为今后的杂种优势利用提供理论依据。

Abstract:

In order to use sorghum lines better in the future of cross-breeding, 120 sorghum lines were studied in 5 agronomic traits by cluster analysis and statistical analysis. The results showed that low coefficient of variation of the whole growth period, plant height, ear length coefficient of variation of the main medium, 1000-grain weight and grain weight per spik were influenced significantly by the environment, so these traits can be used in cross-breeding and selective breeding. The 120 sorghum varieties could be divided into 2 groups and could be further divided into 6 sub-class, have their own characteristics of each sub-category for the future to provide the theoretical basis for heterosis.
