Assessment of genetic diversity among tomato (Solanum lycopersicum) genotypes under salt-affected conditions
Abstract
The experiment was conducted in a randomized block design with 38 genotypes (including three checks) of tomato (Solanum lycopersicum L.), in three replications for thirteen quantitative traits. The analysis of variance showed that mean squares due to genotypes were significant for all the characters. Based on the Mahalanobis D2 statistics, 38 genotypes were grouped into 15 clusters. The maximum number of genotypes (9) were grouped into Cluster I. The highest inter-cluster distance was observed between Cluster XI and Cluster VI, indicating that crossing genotypes from these two clusters is likely to produce highly heterotic and diverse segregants. Highest percent contribution towards clustering of genotypes were observed in total soluble solids, followed by unmarketable fruit yield/plant, average fruit weight and equatorial diameter of fruits.
