In the present study generation mean analysis 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 8 quality traits. analysis of variance was carried out for 8 quality traits. Highly significant difference observed among treatments, for all the characters except protein content (%) and stearic acid. Highly significant difference observed among parents, for all the characters except seed yield per plant (g), protein content (%) and palmitic acid. Highly significant difference observed among F1s, for all the characters except oil content (%), stearic acid, oleic acid, linoleic acid and linolenic acid. Highly significant difference observed among parent vs crosses, for all the characters except protein content (%). Useful heterosis over better parent and mid parent the best crosses. viz., NPRR271 X NO 356 and RL-28-1 X L-53 for oil content (%) were considered. Medium heritability was observed in characters like palmitic acid, linoleic acid and linolenic acid, whereas low heritability was observed in characters like seed yield per plant (g), oil content (%), protein content (%), stearic acid and oleic acid. In F1 generation characters likes palmitic acid and oleic acid exhibited high value of genetic advance.
