Abstract The present investigation entitled “Evaluation of progenies of tomato (Solanum lycopersicum Mill.) hybrid for yield, quality and resistance to Tomato Leaf Curl Virus (TLCV) disease†was undertaken to study the extent of variability, heritability (b.s.), genetic advance, correlation and Tomato Leaf Curl Virus (TLCV) disease incidence of 10 tomato progenies along with one check and two parents. These progenies were planted in Randomized Block Design (RBD) with three replications during autumn-summer season 2010 at All India Coordinated Research Project on Vegetable Crops, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Dist- Ahmednagar. The observations were recorded for various quantitative characters viz., plant height, days to initiation of flowering, days to 50% flowering, days to first harvest, harvesting duration, fruit yield per plant, average fruit weight, average fruit diameter, number of locules, pericarp thickness and total soluble solids and qualitative characters like plant growth habit, leaf type and fruit ripening colour. Disease incidence observations were recorded after 30 DAT at an interval of 15 days upto 120 DAT including susceptible check as Punjab Chuhhara. Appreciable amount of variability was observed for all the characters under study. The genotypic coefficient of variation was highest for fruit yield per plant (23.45%). The phenotypic coefficient of variation was highest for fruit yield per plant(25.11%) followed bynumber of locules indicating presence of good amount of genetic variation for these traits which can be further effectively exploited in future crop improvement programme. Heritability (b.s.) was high for average fruit weight (89.8%) followed by fruit yield per plant (87.2%) and total soluble solids (83.2%). The high genetic advance was observed for average fruit weight (23.15%) and moderate for plant height (11.60%). The high heritability along with high genetic advance was also recorded for the above mentioned characters. The character with high heritability associated with high genetic advance may be attributed to the additive gene effect and suggests a simple selection these characters can be improved.
