Abstract

Variance components and character association of economic traits were analyzed in 31 genetically diverse genotypes of tropical cabbage (Brassica oleracea var capitata) during 2012-14. Wide range of variability was observed for important economic traits like net head weight, gross plant weight and number of non-wrapping leaves. High heritability coupled with high genetic advance was observed for days to harvest. Net head weight showed significant positive correlation with days to harvest, plant spread, gross plant weight, leaf width, leaf length, head width, stalk length and number of wrapping and non-wrapping leaves. The significant positive inter relationships point to the need for simultaneous selection among these characters for improvement of yield. Path analysis showed that gross plant weight, leaf length and head width are the characters to be considered in direct selection for genetic improvement in tropical cabbage.
