Genetic variability study was conducted in some quantitative traits of tomato. The cultivars were evaluated under greenhouse and field conditions at the University of Ghana Forest and Horticultural Crops Research Center (FOHCREC) in Ghana. The experimental layout in each location was Randomized Complete Block Design (RCBD) with three (3) replications. The individual analysis of variance performed for the data gathered revealed a significant (P < 0.01) variability among the cultivars for most of the traits. Variance components estimated on individual location basis indicated a moderate to high genotypic coefficient of variability (GCV), high broad sense heritability as well as high genetic gain for most of the traits. The present study provides significant information for selecting desirable cross combinations for conventional breeding targeting yield improvement of tomato in Ghana.
