Soybean occupies, as importance, the first place in the group of grain legumes due to its use in human nutrition, as a source of very good protein and oil quality, as herb and because it is a very good prior plant to the ground, leaving a reserve of 80 to 140 kg N/ha. Heterosis and combining ability studies were carried in 54 crosses derived from crossing of 18 soybean lines with 3 testers. Based on various estimates viz., mean performance, heterosis and combining ability the best soybean parents and crosses for quality traits were identified. Combining ability analyses indicated that Shivalik showing the largest general combining ability (GCA) effect for protein and oil contents was the best combiner, and identified several best cross combinations with high positive specific combining ability (SCA) effects. These crosses involved geographically diverse parents and at least one parent of high General Combining Ability (GCA) effects in combination of high x high, high x average and high x low. Therefore, these crosses could throw transgressive segregants in still advance generations. The results of present study suggested that heterosis coupled with high SCA effects might be considered as criteria for selecting crosses for further improvement with respect to quality traits.
