Estimates of heterosis for yield and its attributing traits in tomato (Solanum lycopersicum L.) crop
Nishakant Maurya and GC Yadav
The investigations were carried out to evaluate the heterotic performance of 35 F1's in tomato (Solanum lycopersicum L.) at Main Experimental Station, Department of Vegetable Science, A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi 2019-20 and 2020-2021. The experiments were laid out in a Randomized Complete Block Design with three replications. The data were recorded for 17 characters including total fruit yield per plant and its component traits. The analysis of variance indicated significant differences among parents and hybrids for majority of the characters reflecting the presence of adequate genetic diversity in the materials studied. Based on estimates of heterosis, the hybrids 2012/TLCVRes-1-2 × NDT-4 and 2013/TODVAR-2-2 × NDT-2-2 in Y1, Y2 and pooled showed significant and positive heterobeltiosis while, NDT-6 × Arka Vikas, NDTH-11W-9-1-1-1 × NDT-4, 2013/TODVAR-2-2 × NDT-2-2, 2013/TODVAR-2-2 × NDT-5 and S5 × NDT-3-2-1-1 × NDT-2-2) in Y1, Y2 and pooled showed significant standard heterosis in positive direction for total fruit yield per plant and its other component traits hence, could be utilize in future breeding program as hybrid or to obtain most desirable segregants for the development of superior genotypes.
