The present investigation on variability and correlation studies in radish (Raphanus sativus L.) was carried out at the research field of Division of Olericulture, SKUAST-K, Shalimar Campus Srinagar during the year 2002 at 3 different dates viz., 22.3.2002, 24.5.2002 and 29.8.2002. The analysis of variance revealed highly significant differences among genotypes for different characters during the different sowings. Both phenotypic as well as genotypic coefficient of variation were high for all the characters except for days to maturity and vitamin-C content. Heritability in broad sense was high for all the characters. Genetic gain was maximum for root length followed by shoot to root ratio. Root weight was significantly and positively correlated with days to maturity, leaf number, leaf weight, root length, root diameter, total dry matter and total soluble solids while it showed negative significant correlation with top to root ratio both at phenotypic as well as genotypic levels. The root length showed maximum direct effect on root weight followed by root diameter and leaf weight. In general no significant differences were observed in the characters studied from the individual sowings and the pooled analysis.
