Popis: Fifteen pure breeding line of Tomato (Lycopersicon esculentum Miller) were crossed with two tester. Genetic analysis was carried out to detect the epistasis and to estimate component of genetic variation for three qualitative traits. The epistasis was important for all the characters under study except total soluble solid in autumn – winter season. Significant estimate of both additive (D) and dominance (H) component were significant for number of seeds/fruit and number of loculs/ fruit for both the seasons except Total soluble Solids which is significant for additive variance in spring-summer season. The F value positive and significant for Total soluble solids showing isodirectional nature of dominance. Significance of additive component and F parameter showing increasing effect on the character indicating that pedigree selection would be effective for the improvement of such traits.
