Genetic variability and character association analysis in cabbage hybrids.

摘要

The analysis of variance indicated that the difference due to genotypes were highly significant for all the characters. Data further revealed that of the characters under study exhibited high degree of PCV revealing close relationship between phenotypic and genotypic and these characters are not influenced by environment. Maximum heritability was observed in leaves width followed by leaves weight and number of leaves. Leaf length had positive significant correlation with leaf width, leaf weight as well as with head length. Head length had significant correlation with head width. Net head weight expressed significant positive values with leaf length followed by leaf width. Hierarchical cluster analysis showed 2 clusters. Twenty four hybrids divided into 2 clusters with 19 and 5 genotypes respectively. These 19 genotypes further classified into 7 and 12 genotypes, while 7 genotypes further sub-divided in two more stages. The genotypes Kranti, BC-73, Pusa Drum Head and Delhi Ball 65 were different from other hybrids evaluated.
