摘要: 从浙江沿海地区采集到白菜农家资源22份,通过63个形态性状和农艺性状的鉴定评价,对资源间进行了欧氏距离测定和聚类分析,表明了浙江沿海地区白菜资源的多样性,33个质量性状的表型出现率为69.5%,30个数量性状的变异系数平均为26.2%;22个资源中以质量性状计算的欧氏距离平均为5.8,最小的为0;聚类结果表明在距离5处可以把22个资源分成3类;综合比较认为有3对材料极为相似,有同种异名的可能性。

Abstract: In this study, the genetic diversity of 22 varieties of Chinese cabbage in coastal area of Zhejiang province was investigated based on 63 morphological and agronomical traits. The results showed that the phenotypic occurrence rate of 33 qualitative traits was up to 69。5%, the variation coefficient of the other 30 quantitative traits was average at 26。2%. The inter\|variety Euclidean distance, based on the qualitative traits, was estimated ranging from 0 to 5。8. The cluster analysis suggested that the 22 Chinese cabbage could be divided into 3 groups. In addition, 3 pairs of varieties were identified highly similar, therefore implying their possibilities of synonym.
