Abstract:: The genetic diversity was studied on 50 kinds of non-heading Chinese cabbage germplasms based on 12 quantitative characters and 8 qualitative characters.The results showed that the variable coefficient of 12 quantitative traits was among 20.69%-71.68%，and the average value was 34.30%.The widest variation was found in plant weight which had a coefficient of variance 71.68%，leaf width was the smallest.The principle analysis showed that 20 characters were integrated into 4 principle components and their additive contributing rate came up to 80.092%，especially the yield factor(57.257%).By cluster analysis，50 materials were clustered into 3 groups.
