Abstract:

The present investigation was under taken for 10 lines and 3 tester using line x tester mating design consisted of 46 entries including 10 lines, 3 testers, 30 hybrids and three checks viz., CSV 23, CSV 27 and CSH25. These were evaluated in RBD with three replications during kharif 2015 in four environments created by using different spacing viz., 22.5 x 5 cm (E1), 30 x 10 cm (E2), 45 x 10 cm (E3) and 60 x 10 cm (E4). The analysis of variance for L x T mating design in individual environment revealed significant differences between genotypes for most of the characters in most of the environments. The Bartllet test revealed homogenous error variance for plant height and ear head length. The pooled analysis revealed significant differences between the environments, genotypes, parents and crosses for both the characters. This indicates presence of significant variability for these characters. In 22 stable genotypes for plant height line L4 and crosses L2 x T1 and L4 x T2 having bi = 1 for rest of the 19 genotypes bi neither deviating from zero nor from unity. Similarly, for ear head length out of 29 stable crosses L2 and L8 x T2 having bi > 1 and T1, L8 x T2, L4 x T2 and check CSV 27 having bi = 1. In rest of the genotypes bi were not significant. ICSA 29004 × SPV 1822 (L2 x T3) and ICSA 29012 × SPV 1822 (L6 x T3) were identified for multilocation testing as these were having economic heterosis more than 15 per cent for grain yield and dry fodder yield, good SCA, involving one good GCA parents, nicking in flowering in normal spacing environment and male parent taller than the female parent.
