The present investigation entitled Genotypic correlation and path coefficient analysis of yield and its components in Radish (Raphanus sativus L.) under Kashmir valley was carried out during Rabi 2011-12 at the Research Farm Division of Vegetable Science SKUAST-Kashmir in a Randomized Block Design with three replications. Observations were recorded on growth, root yield component and quality traits. Correlation studies revealed that root weight was positively and significantly correlated with leaf number, leaf length, leaf width, leaf weight, root length, root diameter, yield plant-1, total dry matter of roots, vitamin C while negatively and significantly correlated with shoot to root ratio and total soluble solids at both phenotypic and genotypic levels. The result of path analysis revealed that characters like leaf weight, leaf number, leaf length, root length and root diameter showed maximum direct effect towards average root weight. Hence, these traits should be given more emphasis while selecting genotypes for root yield improvement.
