摘要
运用数学方法对矮牵牛S4代13个自交系的花径、株高等9个数量性状进行了性状相关、方差及聚类分析.结果表明:营养器官、生殖器官内部以及两者之间,均有部分性状的显著相关;对于差异分析的6个性状,除株幅外,其它5个性状在其各个自交系内的差异不显著,6个性状在自交系间的差异显著;以9个性状为基础,最小距离为0.6左右,13个自交系归为2大类.
The main characters of 13 selflines of Petunia hybrida in generation S4, such as flower diameter, plant height and other ornamental quantitative characters, were investigated with the mathematical methods of analysis of variance, correlation analysis, and cluster analysis. The results indicate that: 1) There are obvious correlations between any characters wherever they are within nutrient organs, or within reproductive organs or between them; 2) For the six traits analyzed with analysis of variance, they are not significantly different except for the plant crown among selflines and they are significantly different between selflines; 3) According to the nine traits and cluster analysis, the 13 self lines can be clustered into two groups.
