摘要

摘要: 对61份花椰菜种质资源的形态标记进行遗传多样性分析,结果表明:15个形态性状在不同种质材料之间有明显区别,平均变异系数为68.10%,说明这些形态学性状具有较大的变异潜力;前5个主成分的贡献率为73.21%,说明前5个主成分已经包含了所有形态标记73.21%的内容,因此,选取前5个主成分为花椰菜形态性状的重要主成分;在阈值为0.77时,可以将61个品种分为4组,聚类结果在一定程度上能够将来自不同地区和不同熟性的品种材料分开。

Abstract: Sixty one genotypes of cauliflower germplasm were analyzed for genetic diversity based on the morphological markers in this study. The results showed that there are obvious differences among 15 morphological characters in different germplasms, the average coefficient of variation was 68.10%, and it declared that they had a great potential variation. The first five principal components of the contribution rate was 73.21%, it indicated that the first five principal components contained all morphological markers to 73.21% of the content, so the first five principal components of cauliflower morphological traits were selected, 61 varieties could be divided into four groups according to threshold of 0.77. The results showed that clustering was able to separate the materials of coming from different areas and different maturing in a certain extent.
