摘　　要：4个苏丹草(Sorghumsudanense)品种和6个高粱(S.bicolor)品种被用来进行高粱和苏丹草的比较研究。结果表明,定性性状22,24,31在高粱与苏丹草上表现完全一致;数量性状除3,9,13,15,19,27,38,41,42,46,47,48,49,57在2类间差异不显著外,其余皆达显著或极显著水平。高粱与苏丹草品种间F测验达极显著水平,但苏丹草品种内1与2,3的F测验不显著,高粱品种6,7,10间F测验不显著。全部个体判别分析表明,各品种回判正确率为100%。聚类分析表明,参试的10个品种被明显分成2类,即苏丹草1,2,3,4聚为一类,高粱5,6,7,8,9,10聚为另一类。数量指标的方差分析显示,聚类指标的选择是合理的。66 biological characteristics were looked at for a comparative study between sorghum ( Sorghum (bicolor) ) and sudangrass ( Sorghum sudanense ) by means of variance, discrimination and cluster analyses. (Significant) differences in biological characteristics between sorghum and sudangrass were found. The F -test (divergence) values between the varieties of sorghum and sudangrass were mostly highly significant. (Discrimination) analysis of all plants suggested that 100% of originally grouped cases were correctly classified. Cluster analysis showed the 10 varieties of sorghum and sudangrass in the study fell into 2 groups, namely four sudangrass varieties making up one kind, and six sorghum varieties making up the other. Analysis of variance showed the characteristics chosen for cluster analysis were reasonable.
