Abstract:
Superior lines of tomato viz., PKM-1, IIVR-Sel-1, BL-342-1, CO-3, H-36 and SB-10 crossed with testers viz., DARL-62, Bilahi-2, DARL-63, BT-120, Swarna Naveen, BT-1, LE-66, H-86 and Punjab Chhuhara in line x tester mating design to develop 54 hybrids to study average heterosis, heterobeltiosis and also economic heterosis for yield and yield attributing traits in tomato (Solanum lycopersicum L.). The experiment laid out in randomized block design, at Saidapur Farm, Division of Horticulture, University of Agricultural Sciences, Dharwad. Among the hybrids, two out of fifty four hybrids showed highest per se value in order of ‘H-36 x BT-1’ and ‘H-36 x LE-66’ expressed significantly positive average heterosis and heterobeltiosis while ‘H-36 X BT-1’ exhibited higher per se for total yield per plant and significant positive average heterosis, heterobeltiosis and also economic heterosis.
