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.

Key words: Chinese cabbage, local variety, genetic diversity, cluster analysis, Zhejiang
