Evaluation of Genetic Divergence Analysis in Tomato (Solanum lycopersicom [Mill] Wettsd)

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.

Assessment of growth and yield parameters in recombinant inbred line populations of tomato (Solanum lycopersicum L.) through correlation and path analysis

“…The characters such as days to first flowering (-0.679) and 50% flowering (-0.246) showed negative significant correlation, indicating that these attributes are highly influence fruit yield in tomato and therefore, important for bringing improvement in fruit yield. The relationship between fruit yield and fruits per plant and average fruit weight was also reported (Yadav et al, 2020;Sharma et al, 2021). The remaining characters are positive but nonsignificant viz., number of locules per fruit, fruit length, and fruit diameter doesn't have effect on fruit yield.…”
