Abstract
The present investigation was carried out to estimate the genetic diversityfor11 yield contributing traits among 50 genotypes of tomato (Solanum lycopersicom [Mill.] Wettsd.) during 2017 in Randomized Block Design with three replications. In this context maximum intra cluster distance was recorded within cluster III and inter cluster distance was recorded between cluster I to V III. Cluster III had maximum number of genotypes. Major cluster in divergence analysis contained genotypes of heterogeneous origin, thereby indicating no parallelism between genetic and geographic diversity. Therefore, crosses between members of clusters separated by high inter- cluster distance are likely to produces desirable segregates.
