An experiment was conducted to study the variability for ascorbic acid, beta carotene and minerals content (phosphorous, potassium and calcium) in knolkhol (Brassica oleracea var. gongylodes L.) genotypes under sub-tropical condition of Jammu, at Vegetable Research Farm, SKUAST-J, Main campus, during the year 2016-17. High heritability (>70%) was estimated for all the quality traits and moderate for marketable knob weight/plant. High genetic advance as percentage of mean coupled with moderate to high heritability were obtained for beta carotene contents of knob, calcium contents of knob and marketable knob weight/plant indicating thereby that the selection based on phenotypic performance could be effectively utilized for isolation of superior genotypes. | Variability for ascorbic acid beta carotene and minerals content Phosphorous Potassium and Calcium in Knolkhol Brassica oleracea var. gongylodes L. genotypes
