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.
