Stability analysis in tomato (Solanum lycopersicum L.)

Abstract

The experimental materials consisted of 65 entries (48 hybrids, 4 female lines, 12 testers and one standard check i.e. Arka Rakshak) were evaluated in a Randomized Complete Block Design with three replications under three artificially created environments during kharif-rabi season of the year 2016-17 at Main Vegetables Research Station, Anand Agricultural University, Anand to estimate stability parameters in tomato. The performance of genotypes over environments could be predicted reasonably for fruit yield per plant, number of fruits per plant, fruit weight, shelf life, total soluble sugar, lycopene content and β-carotene content, as the G × E interactions and G × E (linear) components were significant for these traits. The result on stability parameters revealed that among the hybrids, AT 3 × TBK 00113 for fruit yield per plant and fruit weight; AT 3 × ATL 11-05 for number of fruits per plant and lycopene content; AT 3 × VTG 93 for shelf life, total soluble sugar lycopene content; while, GT 2 × ATL 11-05 for shelf life and β-carotene content were found stable for varying environments.
