Abstract

Twenty one genotypes of radish were evaluated in Rabi seasons of 2014-15 for different horticultural traits. The phenotypic and genotypic coefficients of variation were found moderate for root weight without leafs, leaf weight, root weight with leafs, root diameter and root length. High heritability coupled with moderate genetic gain observed for root length, root weight with leafs, root weight without leafs, leaf weight and root diameter. The phenotypic and genotypic correlation coefficients among different characters showed that marketable root yield per hectare had positive and significant association with root weight without leaf, root weight with leaf, root length, number of leaves and length of whole plant. The path coefficient analysis revealed that maximum positive direct effect towards root yield per plant was contributed by root weight without leaf, length of whole plant, root weight with leaf, number of leaves, thereby indicating the importance of these traits for yield improvement in radish through direct or indirect selection.
