Studies on Combining Ability Analysis for Yield and Yield Related Traits in Tomato (Solanum lycopersicum L.)

Chandanshive Aniket Vilas, Rana MK, Dhankar Sk, Vikash Kumar and Neha Yadav

An experiment on combining ability for yield and yield related traits of 50 F1 hybrids of tomato derived from the crosses between 10 lines and 5 testers through line x tester technique was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during 2012-13 and 2013-14. The F1s and parents were grown in randomized block design with three replications. In most of the traits, over-dominance was predominant. The analysis of genetic variance for yield components showed that the main part of genetic variance was due to additive effect. Among the lines, EC 620533 was the promising line, EC 620534 the better general combiner and EC 620391, BBWR-10-3-17 and BBWR-11-1 the good general combiner. Among testers, Punjab Chhuhara was better general combiner for number of branches per plant and total number of fruits per plant followed by Arka Meghali and Palam Pink, which showed significant gca effect. Among crosses, BBWR-11-1 x Palam Pink was the better general combiner for the above traits.
