Abstract:
A field trial was conducted to study the effect of heterosis on yield contributing parameters at Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during Rabi 2019-20 and Kharif 2020-21.Forty F1 hybrids were obtained through line x tester mating design by crossing five CMS lines with eight restorer lines during Rabi 2019-20. Their evaluation was carried out during Kharif 2020-21 which consisted of 56 genotypes including 40 F1 hybrids, 8 restorer lines, 5 maintainer of CMS (B lines) and 3 standard checks, laid out in Randomized Block Design with three replications. The analysis of all the characters under study indicated significant differences among the genotypes, parents, hybrids and parents vs hybrids which indicated the presence of substantial genetic variability among the genotypes for the characters studied.

Significantly higher average heterosis and heterobeltiosis for seed yield was recorded by hybrid combination CMS-248A x 189/1R followed by CMS 102A × AKSF-5R. The hybrid CMS-102A × AKSF-5R displayed highest magnitude of standard heterosis for seed yield and was found to be statistically at par with the hybrids CMS-108A × 3/148R and CMS-102A × 3/147R over all the three checks.
