Genetic variability and selection parameters for different genotypes of radish (Raphanus sativus L.) under valley condition of Uttarakhand

Twenty genotypes of radish (Raphanus sativus L.) were evaluated to study the genetic variability, heritability and genetic advance in radish at Experimental Farm of Horticultural Research Centre, H.N.B. Garhwal University, Srinagar (Garhwal), Uttarakhand (India) during Rabi season 2010–11. The analysis of variance revealed highly significant differences among genotypes for almost all the traits. Both genotypic as well as phenotypic coefficients of variation were high for number of leaves, leaf weight, total plant weight, root yield/plant, acidity, ascorbic acid. Heritability in broad sense was high for leaf weight, number of leaves, total plant weight, root weight, total soluble solid and ascorbic acid. Genetic advance in per cent of mean was maximum for root yield/plant followed by leaf weight.
