This study was carried out at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1990. F₁ and F₂ generations from crosses between four determinate soybean cultivars of male parents(Hwangkeumkong, Jangyeobkong, Paldalkong and Suwon 148) and two indeterminate soybean cultivars of female parents(Clark and L63-2404) were used as materials to study on the inheritance of growth characters and yield components. Heritability estimate for days to maturity was fairly high. Stem height, number of nodes on mainstem and mainstem dependence rate of number of nodes and pods had relatively high heritabilities. The heritability of branch-related and yield-related characters was low. Genotypic and phenotypic correlations were significantly positive between seed weight per plant and most of growth or yield components except 100-seed weight. But highly negative correlations were existed between seed weight per plant and mainstem dependence rate of number of nodes and pods. Path corefficient analysis revealed that number of seeds per plant had the greatest direct effect on seed weight per plant, while the total number of nodes per plant and number of nodes on branches showed the greatest direct effects on the number of seeds poer plant.
