Heterobeltiosis and standard heterosis for seed yield, oil content and fatty acid profile was studied in 45 crosses developed through half diallel mating design involving 10 parents. The range of standard heterosis and heterobeltiosis was from-16.38 to 43.34 and 22.24 to 105.32 respectively. The cross combination JSF1 x A2 (45.34) and AKS/S41 x JSF1 (42.40) recorded significant positive standard heterosis over check AKS 207 for seed yield/plant. For character like oil content, oleic acid, linoleic acid and palmitic acid moderately low to low amount of heterosis was recorded for oil content. JSI 99 x NARI 34 (13.48) recorded highest standard heterosis while JSI 97 x A2 (19.54) and AKS/GMU 2724 x JSF1 (9.04) with highest standard heterosis for oleic and linoleic acid respectively. Parents JSF1 and AKS/41 were associated for developing top heterotic crosses for seed yield/plant and these can be utilized in hybrid development programme. High heterotic crosses expected to produce transressive segregant in subsequent generation.
