The current study, "Heterosis for Yield and Yield Components in Tomato (Lycopersicon esculentum L.)," was carried out at the Department of Vegetable Science in Kalyanpur, Kanpur, during the Rabi season of 2022–2023. The experiment was set up using a randomized block design (RBD), with nine parents and eighteen hybrids making up the number of treatments, or genotypes.T1–6026 x Azad T-3, T2- 6026 x Azad T-6, T3–6026 x Azad ks–07, T4–6512 x Azad T-3, T5–6512 x Azad ks–07, T6–7039 x Azad T-3, T7–7039 x Azad T-6, T8–7039 x Azad ks–07, T9–7053 x Azad T-3, T10–7053 x Azad T-6, T11–7053 x Azad ks–07, T12–7048 x Azad T-3, and T13–7048 x Azad T-6. T15- 7202 x Azad T-3 T14- 7048 x Azad ks-07 T-6 T17 7202 x Azad ks-07 T167202 x Azad KS-03 x Azad T187202. The study's findings showed that the highest plant height measured was 103.19 cm (Azad T-6), and that the number of primary branches per plant among the parents ranged from 2.45 (7039) to 4.26 (7048). The parent with the longest fruit length was 6512 (5.45 cm), and the maximum fruit width was 6026 (5.24 cm). Among the crosses, the results varied to 10.66 (7053 × Azad ks-07) to 16.64 (7053 × Azad T-6). Azad ks-07 (15.92) was the parent deemed to be the best in terms of fruit clusters per plant. The other three top parents in terms of fruit production per plants was 7048 (48.70), 7053 (46.96), and 6512 (33.55). Fruit yield per plant was recorded to be 1874.36g (6512 × Azad ks-07), highest number of seeds per fruit were 7053 (148.66).
