Abstract

Seventy one genotypes of tomato were evaluated during 1993–94 and 1994–95. Significant differences were observed for all the characters studied. Based on Mahalanobis D2 values, genotypes were grouped into 9 clusters in 1993–94 & 10 clusters in 1994–95. Fruit weight showed maximum contribution to the genetic diversity in both years followed by plant height. Considering cluster distances and cluster means the genotypes KS-7, DVRT-2, Antey and PS-1 were recommended the best parents for hybridization.
