Abstract:
The evaluation of the extent of heterosis of 12 characters in 15 hybrids of sesame obtained by crossing 5 lines and 3 testers in line x tester method was performed at farmers field, ORARS (KAU) Kayamkulam. Highly significant variations were visible for all of the genotype characters when analysis of variance was done. The spectrum of standard heterosis for seed yield plant^-1 ranged from -69.46% to 78.57%. The five hybrids viz., Gu. Til 4 x NIC-8322, Gu. Til 4 x PCU-41, RT-346 x PCU-37, VRI-3 x PCU-41 and Punjab Til No.2 x PCU-37 recorded significant positive standard heterosis over the check for seed yield plant^-1.
