영문 초록

This experiment was carried out to get the genetic information for increase breeding efficiency in soybean. Six soybean varieties were used as diallel-cross materials to investigate the inheritance of flowering and maturity. Incomplete dominance with large additive effect was present according to the genetic parameter of variance component for days from planting to flowering(DPF) and days from planting to maturity (DPM). The DPF was ruled by more recessive alleles and DPM by more dominant alleles. A few genes were thought to govern the DPF and DPM. By Wr/Vr graph analysis, relevant genes for DPF and DPM acted as partial dominance and the dominance order of parents was changed along with generation. Okuhara wase was dominant in DPF, while Paldalkong was recessive. Yuhsuzumi and Danyeobkong were dominant in DPM, while Okuhara wase and Paldalkong were recessive. By the generation mean analysis, all three soybean crosses revealed that additive gene effect was significantly high in both DPF and DPM. F₂ individuals in all three soybean crosses showed continuous normal distributions of DPF skewed to late parent and transgressive segregations of DPF over the early or late parent. F₂ distributions of all three crosses for DPM were also continuous ones having central peak near mid-parent with transgressive segregations mainly toward to the earlier direction over the early parent. All genotypic correlation coefficients was higher than phenotypic one and interrelationships among DPF, days from flowering to maturity(DFM) and DPM was closely associated. Broad sense heritability was fairly high for DPF(0.645) and DPM(0.678) in F₂.
