Generation mean analysis with six generations, a set of 60 treatments (10P1, 10P2, 10 F1, 10 F2, 10 BC1 and 10 BC2) was chosen to study the nature and magnitude of gene effects for seed yield and yield attributing traits. The studies were undertaken on Randomized Block Design with three replications in Rabi 2015-16. The range of heterosis over better parent was observed from 9.07 to 50.57 per cent. Three crosses namely, NPHY 29 X LCK 87312, NP121 X RR 76 and NPRR271 X NO 356 showed significant positive heterosis. The heterosis over mid parent varied from 7.77 to 50.42 per cent. Out of 10 crosses three cross NPHY 29 X LCK 87312, NP121 X RR 76 and NPRR271 X NO 356 showed significant positive heterosis. The range of inbreeding depression varied from 14.78 to 53.37 per cent. Three crosses, NPHY 29 X LCK 87312, NP121 X RR 76 and NPRR 271 X NO 356 showed significant increase. For oil content (%) The range of heterosis over better parent was observed from -12.91 to 11.18 percent. Out of 10 crosses, only one cross NPRR 402 X NP 8 showed significant positive heterosis. The range of inbreeding depression varied from -0.92 to -9.10 per cent. Three crosses, NP121 X RR 76, RL-28-1 X L-53 and AHUDEARA 170 X SJKO 05. Showed significant decrease while three combinations namely, NPHY 29 X LCK 87312, NPRR 271 X NO 356 and NPRR 402 X NP 8 showed significant increase. Native estimates of heterotic effects may be observed in some traits may be attributed to inter-allelic interactions.
