Abstract
The present investigation entitled “Performance of Radish (Raphanus sativus L.) genotypes for yield and qualitative traits at Experimental and Farmer’s Field” was carried out during Rabi 2011-12 and Rabi 2012-13 at the Research Farm Division of Vegetable Science SKUAST-K and the identified promising genotypes on Farmer’s field in a Randomized Block Design with three replications. Observations were recorded on growth, root yield component and quality traits. The analysis of variance was highly significant for all the traits indicating presence of high variability in the genotypes. The high heritability in broad sense was associated with high genetic advance as percent of mean for leaf length, leaf weight, leaf width, leaf number, root weight, root diameter, root length, yield plant-1, shoot to root ratio, vitamin C and total dry matter of roots. 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. CO-1, Kalayani White, HK-111, White Round, Japanese White Long and IIVR-1 were found promising and best genotypes and Anantnag Red Round and Chinese Pink were promising and better genotypes for qualitative traits on farmers fields and may be used in further breeding programme.
