Studies of Genetic Variability, Heritability and Genetic Gain for Some Important Horticultural Traits in Cauliflower (Brassica oleracea var. botrytis L.)
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2018, Vol 7, Issue 4
Abstract
Twenty mid-late and late group cauliflower genotypes were evaluated during Rabi season of 2016 at the Experimental Farm of the Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Solan, Himachal Pradesh. The objective was to estimate the nature and magnitude of genetic variability, heritability and genetic gain of ten important horticultural traits. The magnitude of PCV was higher than the corresponding GCV for all the characters studied. Moderate estimates of GCV was recorded for leaf number per plant (19.12%), curd depth (15.76%), plant height (20.85%), leaf size index (19.44%), curd size index (26.51%), gross weight per plant (19.56%), and marketable yield per plant (18.63%). High heritability (>80%) coupled with high genetic gain (>50%) was noted for the trait curd size index whereas high heritability coupled with moderate genetic gain was found in the traits like leaf number per plant, curd depth, leaf size index, gross weight per plant and marketable yield per plant. These indicated presence of sufficient variability in the germplasm, predominance of additive gene action and high transmissibility of the characters. So that, direct selection will be rewarding depending upon these traits.
