主成分分析을 利用한 콩의 播種期別 開花 및 成熟反應에 따른 品種分類
Chang Hwan Cho(曺章煥),Yeul Gue Seung(成烈圭),Seang Min Kim(金成敏) 한국육종학회 1994 한국육종학회지 Vol.26 No.4
This experiment was carried out to know the varietal difference of elcological variation in flowering and maturity through five times planting from April 20 to July 10 with 20-day interval for 1991-1992. Tested fifty five soybean genotypes were classified into three or four groups based on seasonal response of flowering and maturity by principal component analysis. The upper two principal components for DPF (days from planting to flowering), DPM (days from planting to maturity), and yield per plant contributed about 96, 95, 63 percent of respective total variances. Fifty-five soybean genotypes were roughly classified into four groups by the response of flowering and three groups by the response of maturity and yield per plant, respectively. The variation of DPF at different planting time in Ⅰ and Ⅱ Group was smaller than that that in Ⅲ and Ⅳ Groups, and the shortened degree of DPM along with planting time in Ⅰ group was smaller than that in Ⅱ and Ⅲ Groups. Decreasing degree of yield per plant by late planting in all groups was critical from June 20. Yuhsuzumi and Okuhara wase were seletcted for early flowering and maturity soybean materials. Jangyeobkong and Paldalkong were also picked up for medium ones, and Danyeobkong and Dogyoukong were selected for late ones.

콩 二面交雜 F₁, F₂및 여交雜集團을 利用한 開花ㆍ成熟期 遺傳과 遺傳子作用 分析

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.
