우수한 특성을 가진 나물콩 품종 육성을 위하여 국내 재래 나물콩 계통의 콩나물 특성을 분석한 결과는 다음과 같다. 1. 공시된 301품종 및 계통의 콩나물 전체길이의 범위는 9.5∼23.0cm, 하배축 길이는 5.9∼15.1cm, 뿌리 길이는 3.2∼9.2cm로 다양한 변이를 보였고, 수율에서도 121∼695%로 다양하게 분포하고 있다. 2. 공시된 301품종 및 계통의 종피색에 따른 콩나물 수율은 혼색종피종에서 409%로 가장 높게 나타났고, 백립중에 따른 콩나물 수율은 소립종일수록 높은 경향이었으며, 잔뿌리수는 흑색종피종과 갈색 종피종에서 현저히 적었다. 3. 콩나물 길이와 전체길이에 대한 뿌리길이의 비율, 수율을 기준으로 한 공시품종 및 계통들의 분포에서 장려품종보다 우수한 특성을 가지는 다수의 재래계통이 분포하고 있었다. 4. 콩나물 하배축의 색도는 백색도(L값)에서 장려품종이 재래계통에 비해 백색에 더 가까웠고, 적색도(a값)와 황색도(c값)는 장려품종보다 재래계통에서 높은 경향이었다. To develop good soybean varieties for sprouts. 285 indigenous lines and 16 recommending varieties were evaluated by the sprout and agronomic characteristics. The range of whole length, hypocotyl length, root length, and yield rate of sprouts was 9.5~23.0cm, 5.9~15.1cm, 3.2~9.2cm, and 121~695%, respectively. Yield rate of sprouts was the highest, 409%, in the lines of mixed seed coat color. At the same time, it was reversely proportional to seed weight : the smaller the seed weight, the higher the yield rate as in all other reports. The number of roots was significantly fewer in the lines of the black and the green seed coat color than others. Based on whole length, rate of root length, and yield rate of sprouts, many indigenous lines were evaluated much better than recommending varieties. In the hypocotyl color of sprouts, the brightness was higher in improved variety than indigenous lines but vice versa in redness and yellowness in general.
交配組合의 伸育型에 따른 콩 F_1의 雜種强勢 程度 및 差異

Twenty one F_1 hybrids made out of 22 varieties which are the commonly being used for the soybean breeding programmes in korea were tested for standard heterosis(mid-parent heterosis) and heterobeltiosis(high-parent heterosis). A great deal of differences measured in mid-and high-parent heterosis were recognized among the cross combinations and the attributes measured. Agronomic characters showed high heterosis were the number of branches, the number of branch nodes, the number of pods, and the number of seeds per plant. The mean degree of heterosis for seed yield were 74.8% in mid-parent heterosis and 44.9% in high-parent heterosis, respectively, which were relatively high compared to that of other major self-fertilizing crop species. Cross combinations showed high heterosis were Milyangkong/SS77053-B-B-38-1-2, KAS700-42/SS7053-B-B-38-1-2, SS79168-26-4-2/Williams, and Hwangkeumkong/HHH6-2-2-, which were all crossed between varieties having different growth habit. The degree of hybrid vigor for seed yield was higher in the cross combinations of different growth habits than those of same growth habits. It was espesially high when indeterminate varieties were used as female and determinate ones as pollen parent.
