Fifteen germplasm lines of radish were collected from different parts of Meghalaya, India and were evaluated on the basis of 23 horticultural traits in a randomized block design with three replications at Krishi Vigyan Kendra, ICAR NEH, Sangsangiri, Tura, Meghalaya, India during winter season from October to January (2014-15). Correlation analysis was carried out to study the character association and contribution for ten quantitative characters, namely leaf length (cm), leaf width (cm), number of leaves, petiole length (cm), crown head diameter(cm), root length(cm), root diameter (cm), days to root harvest, root weight (g) and yield (t/ha) for the identification of appropriate selection indices. Phenotypic and Genotypic correlation coefficient analysis revealed that root weight, days to root harvest, number of leaves, root length leaf width, and root diameter had significant positive correlation, while petiole length, leaf length and crown head diameter had significant negative correlation with marketable yield.
