Abstract:

22 varieties Chinese cabbage provided from Xinxiang Academy of Agricultural Science were used as materials,the main agronomic characters(leaf number,leaf length,leaf width,petiole length,leaf thickness,chlorophyll content and fresh weight) of Chinese cabbage and their genetic correlation analysis were conducted,to realize the variations of main agronomic characters and their relationship.The results showed that the coefficient of variation(CV) of the 7 traits ranged from 10.59% to 65.53%,the highest CV was the fresh weight and the lowest CV was the leaf number,and heritability ranged from 57.91% to 97.44%,the highest heritability was the chlorophyll content and the lowest heritability was the leaf number.Except the heterobeltiosis of leaf thickness and chlorophyll were not obvious,the mid-parent heterosis and heterobeltiosis of other traits were obvious.Among 7 traits,the fresh weight had significant correlation with leaf number and leaf length and petiole length.
