Shreya Rini Titus*, Anita Kerketta and Vijay Bahadur Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj Allahabad, U.P., India *Corresponding author ABSTRACT Introduction Tomato (Solanum lycopersicum L., 2n = 2x = 24) is one of the widely grown vegetable crops cultivated for its fleshy fruits in the world. It belongs to the Solanaceae family with other frugally important crops such as pepper, eggplant and potato. Tomato is a rich source of vitamins (A and C), minerals (Ca, P and Fe) and a strong antioxidant against cancer and heart diseases (Dhaliwal et al., 2003). Tomato is protective supplementary food and considered as important commercial and dietary vegetable crop. It is also a good source of polyphenolic compounds, such as flavonoids and hydroxyl cinnamic acids (Bugianesi et al., 2004). It is known as an important source of vitamins and minerals due to adequate vitamins A and C, calcium and iron. Tomato's fruit is consumed in providing salads and cookies. In addition, it is used to can, paste, ketchup, sauce, puree and fruit International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 12 (2020) Journal homepage: http://www.ijcmas.com The genetic materials was consisted of twenty one tomato hybrids. Trial shown in a randomized block design (RBD) with three replications was used. Experiment was conducted at Farm of Dept of Horticulture at Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences Naini, Prayagraj Uttar Pradesh in Rabi season 2019.Mean square due to treatments revealed that significant differences among the hybrids for all the traits except number of fruit set per cluster, fruit weight, number of locules per fruit, number of locules per fruit, fruit shape index and total soluble solid. High GCV and PCV were exhibited for number of fruit yield per plant and leaf curl incidence. High estimate of heritability were exhibited for leaf curl incidence, number of fruit yield per plant, plant height and days to 50% flowering. The genetic advance as percentage of mean was highest for number of fruit yield per plant and leaf curl incidence recorded.So that it is concluded that the characters which showed high GCV, PCV and heritability coupled with genetic advance should be considered for direct selection. Here fruit yield per plant and leaf curl incidence the character under study showed high heritability and genetic advance. Thus one should select these characters for direct selection.
