Determining the contribution of different yield components in broccoli (Brassica oleracea var. italica l.) through character association

Abstract

A total of thirteen broccoli genotypes were evaluated for 14 quantitative traits to ascertain the traits involved in enhancing curd weight. Correlation and path coefficient analysis revealed the direct and indirect of fourteen quantitative characters studied. Estimates of phenotypic and genotypic correlation revealed that the curd yield per hectare to be highly positive and significantly correlated with curd weight / plant, curd length, curd width, leaf dry matter percentage, number of leaves, leaf length and leaf width. Path coefficient analysis of different characters contributing towards curd yield per hectare exhibited highest positive direct effect followed by curd weight/plant, days to curd initiation, leaf width, curd length, curd dry matter, leaf dry matter and Vitamin C. Therefore, these traits have to be considered, while practicing selection aimed at improvement of yield in broccoli.
