Abstract: An experiment was conducted at the Experimental Research Farm, RHR&TS, Jachh, Kangra, Himachal Pradesh to estimate heterosis for quality traits in tomato by involving 10 lines and two testers. The results revealed that the cross, EC-620410 × Solan Lalima had maximum heterobeltiosis as well as standard heterosis for fruits shape index. For number of locules per fruit, the crosses EC-191531 × Solan Lalima and EC-37239 × Solan Lalima recorded maximum negative heterobeltiosis and negative standard heterosis, respectively. BT-1-1× FT-5 showed maximum positive heterobeltiosis pericarp thickness and ascorbic acid content, whereas, EC-37239 × FT-5 recorded maximum standard heterosis for pericarp thickness. The cross, LE-79-5 × FT-5 had maximum positive heterobeltiosis and standard heterosis for total soluble solids content. Based on the results, these superior hybrids may further be tested in multiple locations for yield and quality traits in order to exploit heterosis at commercial level in tomato.
