Genetic divergence studies in tomato (Solanum lycopersicum L.)

Abstract

The present investigation was conducted in randomized block design with 26 genotypes of tomato in three replications. The objectives were to assess the relative performance, estimation of genetic parameters and genetic divergence for fruit yield and yield contributing characters. The magnitude of GCV and PCV was found highest for fruit shape index (35.28&37.46).The heritability estimates were found to be high (more than 70%) for plant height (cm) at 120 DAT (92.00) and fruit shape index (89.00). The high genetic advance was obtained for plant height (cm) at 120 DAT (53.88). Maximum number of genotypes were grouped into cluster 3rd which included 10 genotypes. The intra-cluster distance varied from 22.40 to 69.21. The maximum intra cluster distance was shown by cluster 6 (69.21). In the contribution of each character to divergence showed plant height (cm) at 120 DAT contributes highest (41.23) to divergence.
