tailieunhanh - Genetic variability and D2 analysis for yield and quality traits in tomato (Solanum lycopersicum L.)

Forty two genotypes of tomato including four check cultivar (GT-2, GT-6, JT-3 and Pusa Ruby) were planted in Randomized Block Design, during rabi 2018 and were assessed to know the nature and magnitude of variability and genetic divergence for twelve traits. The experimental results revealed a wide range of variability for all the traits under study. High heritability coupled with high genetic advance was observed for number of fruits per plant, plant height, fruit length, fruit girth, shelf life of fruits, tomato leaf curl virus incidence, average fruit weight, fruit borer damage and number of locules per fruit which offers the better scope for improvement through selection. Based on the Mahalanobis D2 statistics, forty two genotypes of tomato were grouped into three clusters. | Genetic variability and D2 analysis for yield and quality traits in tomato Solanum lycopersicum L.
