Estimation of heterosis for earliness, yield and yield contributing traits in tomato (Solanum lycopersicum L.)
Author(s): T. RAJ, M. L. BHARDWAJ AND S. PAL
Abstract: With an objective to estimate the heterosis for earliness, yield and yield contributing traits in tomato, 20 hybrids were produced from ten lines and two testers and were evaluated. BT-1-1 × FT-5 and EC-191531 × FT-5 had maximum negative heterobeltiosis, whereas, EC-620410 × Solan Lalima showed maximum negative standard heterosis for days to 50% flowering. EC-8910155 × FT-5 recorded maximum negative value for both heterobeltiosis and standard heterosis for days to marketable maturity. BT-1- 1 × FT-5 showed maximum heterobeltiosis for number of fruits per cluster, yield per plant and harvest duration. Moreover, it had maximum standard heterosis for the former two traits. Furthermore, it recorded maximum heterobeltiosis for number of marketable fruits per plant, whereas, LE-79-5 × FT-5 recorded maximum standard heterosis for this trait. BT-1-1 × Solan Lalima had maximum heterobeltiosis and standard heterosis for average fruit weight. LE-79-5 × FT-5 showed maximum negative heterobeltiosis and standard heterosis for severity to Alternaria.
