ABSTRACT
The present investigation entitled “Evaluation of tomato (Solanum lycopersicum L.) genotypes for fruit, yield and quality traits’ was carried out at the vegetable research farm, Guru Kashi University, Talwandi Sabo, Bathinda during year 2020-2021. The experiment was laid out in Randomized Block Design (RBD) with three replications. Thirty genotypes including a check cultivar were evaluated for different horticultural traits. The observations were recorded, number of branches per plant, plant height (cm), average fruit weight (g), equatorial diameter of fruit (cm), polar diameter of fruit (cm), number of locules per fruit, pericarp thickness (mm), fruit pH, fruit TSS (Brix), number of fruits per plant and Average yield per plant (kg). Analysis of variance showed significant differences among genotypes for all the characters under study. Maximum numbers of branches were recorded in Sel Oval (6.01). The maximum plant height 169.00 cm was recorded in the genotype Sel-135. Sel 137 recorded maximum number of fruits per plant (71.30). Maximum average fruit weight was recorded in Sel-137 (104.00g.) as compared to check variety Pb Ratta-167 (68g). Sel IT-8 was found maximum equatorial diameter of fruit (6.13 cm) and maximum polar diameter of fruit (6.10 cm). Maximum number of locules per plant (7) was found in Sel Small Round. Maximum pericarp thickness (7.3 mm) was observed in Sel B1-9. Maximum value for fruit pH (4.60) was recorded in Sel-136. Maximum value for fruit TSS (4.430Brix) was recorded in Sel 15 ob-9. Maximum yield per plant was recorded in Sel B1-9 (3.75 kg).The genotypes SEL-137, Sel 30 and Sel B1-9 gave highest fruit yield.
