Genetic variability of tomato genotypes for yield and other horticultural traits

Sixteen diverse genotypes of tomato (Solanum lycopersicum L.) were evaluated to study the genetic variability, heritability and genetic advanced at Horticultural research farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedker University, Lucknow (India) during rabi season 2011–12. Ten plants were randomly selected from each plot and tagged for recording data on 19 characters. The analysis of variance revealed significant differences among genotypes for all the traits. Both genotypic as well as phenotypic coefficients of variations were high for number of cluster/plant, number of flower/plant, fruit weight/cluster and number of fruits/plant. Heritability in broad sense was high for plant height, number of leaves/plant, number of cluster/plant, number of flower/plant, number of locules and pericarp thickness. Genetic advance in % of mean was maximum for number of cluster/plant followed by number of flower/plant, fruit weight/cluster and number of fruits/plant.
