Mean Performance of Knolkhol (Brassica oleracea var. gongylodes L.) Genotypes for Various Quantitative Traits under Sub Tropical Conditions of Jammu

The present investigation entitled “Mean performance of knolkhol (Brassica oleracea var. gongylodes L.) genotypes for various quantitative traits under sub-tropical conditions of Jammu” comprising of thirty genotypes was carried out at Vegetable Research Farm, Division of Vegetable Science and Floriculture, FOA, Chatha, SKUAST-J, Main campus, Chatha to evaluate the mean performance of knolkhol for various Quantitative traits during the year 2016-17. The field experiment was laid out in Randomized Block Design with three replications, spaced at 30 cm × 30 cm. The analysis of variance revealed that mean squares due to genotypes were significant for all the traits highlighting the presence of sufficient genetic variability among the genotypes. Based on the mean performance of genotypes with respect to various growth and yield attributing genotypes namely SJKK-04, G-40 and Green Gold gave yield statistically at par with Early Super White Vienna which had higher yield among the genotypes studied. SJKK-04 was also found to be one of the best performers for number of leaves per plant, net knob weight per plant and gross knob weight per plant. Genotype Early Super White Vienna had maximum marketable knob diameter and took less number of days to marketable knob maturity and Pusa Virat had minimum stalk length and petiole length, respectively.
