Abstract:

10 lines and 3 tester using L x T 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 viz., 22.5 x 5 cm (E1), 30 x 10 cm (E2), 45 x 10 cm (E3) and 60 x 10 cm (E4) at Rajasthan college of Agriculture, Udaipur in RBD with three replications. 24 crosses exhibited economic heterosis. Therefore these crosses may be identified as superior crosses for these characters. Three crosses L2 x T3, L6 x T3 and L1 x T3 having economic heterosis for grain yield in E2. Where cross L2 x T3 and L6 x T3 also having economic heterosis for dry fodder yield in E¬2. These crosses had good SCA effects and involving at least one good general combiner parent. This indicates superiority of F1 on account of accumulation of dominant genes. Two dual purpose crosses 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. Grain purpose cross ICSA 29003 × SPV 1822 (L1 x T3) is also identified for multilocation testing as it had very high economic heterosis for grain yield (56.65%) in medium spacing environment i.e.30 x 10 cm along with good nicking in flowering and taller male parent.
