This study was conducted to study on the inheritance of growth characters and yield components at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1990. Some quantitative characters in F₁ and F₂ of crosses between four determinate soybean cultivars as male parents(Hwangkeumkong, Jangyeobkong, Paldalkong and Suwon 148) and two indeterminate soybean cultivars as female parents(Clark and L63-2404) were investigated and analyzed for combining ability. In F₁ general combining ability(GCA) of male parents indicating principal contribution of additive genetic effects was significant in stem height, number of nodes on mainstem, number of branches, number of nodes per plant, and mainstem dependence rate of number of nodes. GCA of male and female as well as specific combining ability(SCA) was significant in days to maturity, suggesting that additive and non-additive genetic effects of male and female act simultaneously. Both GCA and SCA effects were not significant in yield components.
In F₂, both GCA of male and SCA effects were significant in stem height, number of nodes, number of pods, mainstem dependence rate, and grain weight per plant. GCA effect of male was significant in number of branhces. GCA effects of both male and female were significant in days to maturity and 100 seed weight. Non-additive genetic effects were shown in number of pods on mainstem, number of pods per plant and number of grains per plant. The significance and directions of GCA and SCA effects varied according to males and females, generations and relevant characters. According to the estimated GCA, Clark and Deogyukong were found to be desirable parents for greater vegetative growth and yield, whereas Suwon 148 for earlyness, Hwangkeumkong for large seed size, and Paldalkong for high mainstem dependence rate and short stem. The estimated SCA effect for yield and lateness was great in the crosses of L63-2404×Dogyukong and Clark×Suwon 148, while SCA effect for earlyness was large in L63-2404×Suwon 148 and Clark×Dogyukong.
