The purpose of this experiment was to classify the varietal groups and to select parents for breeding in sprout soybean. One hundred and thirty three varieties were classified based on 13 chracters measured by Euclidian distance D² and complete linkage cluster analysis was attempted. Ten varietal groups were classified by the complete linkage cluster analysis based on the D² computed in 13 chracters. Group Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ, Ⅶ, Ⅷ, Ⅸ and Ⅹ contained 26 varieties(7%), 9(7%), 6(5%), 4(3%), 9(7%), 22(17%), 2(1%), 39(29%), and 7(5%), respectively. Maturity type of group Ⅷ and Ⅹ, Ⅱ, Ⅲ and Ⅴ, the other groups were classified early, late and medium, respectively, by the day from seeding to flowering. Some varietal groups were associated with their geographical origin. The number of mainstem nodes and chlorophyll content were main contributors to the D² in both intra and inter groups, and the degree of those was not significant.

Bean sprouting is one of the traditional vegitable in Korea. It is producted by sprout soybean cultivars. Experiments were conducted to investigate the major chracteristics in collected sprout soybean cultivars from Chonnam and Chonbuk province farmer’s field. One hundred and thirty three varieties were used in this study. The obtained results were as follows: Average flowering duration were appeared 52 days. On the basis of flowering duration early, medium and late maturing cultivars were devided and they were occupied 9, 75 and 16% of total cultivars tested, respectively. The average chlorophyll content of 12~13th leaf from cotyledon node was 49.5 and the range of chlorophyll content in test cultivars was from 26.5 to 56.2. The height, daimeter of stem and number of nodes in mainstem averged 63.4cm, 7.4mm and 11.2 nodes, and ranged 28~133cm, 3.9~10.3mm 9.0~22.4 nodes, respectively. Average number of branches and pods per plant were appeared 6.2 branches and 85.2 pods, respectively, and those were two times more than those of other collected cultivars for different utlization. One hundred seed weight averaged 8.7g and was appeared smaller seed size than that of other research institute object. Seed coat color in tested cultivars classfied naples yellow, moss green, cream, lemon yellow, black, cocoa, amber and emerald green, and those were 70, 8, 7, 7, 3, 2, 2, and 2%, respectively. Color of hilum classfied black, naples yellow, cocoa, tan, black brown, amber, cream and lemon yellow, and those were 23, 23, 15, 15, 9, 6, 5 and 4%, respectively. Average yield per hectare showed 1,130kg and was lower yield compared to that of improved verieties, but three among all tested cultivars were over 2,400kg/ha. Diameter of mainstem and dry weight per plant were correlated with the 100 seed weight, and those were 0.225, 0.206, respectively. Dry weight per plant, number of pods and diameter of mainstem were highly correlated with yield by 0.743, 0.659, 0.524 respectively.

Sheong Chun Lee,Chan Young Ahn 한국자원식물학회 1999 Plant Resources Vol.2 No.2

These experiments were conducted to evaluate the variability of seed germination and seedling growth with different levels of polyethylene glycol(PEG 6,000) solution in onion seed. Average germination percentage of seed primed in PEG solution with 1.00 and 0.75 MPa was higher than control, and that of seed primed in 1.50MPa was lower than unprimed control. Germination percentage(GP) of seed primed for 5 days was highest, and as the primed days become long, the GP was decreased. The GP of airation seed during the primed was higher than that of unairation seed, about 5%, respectively. The GP of washed seed after primed was higher than that of unwashed seed, but that of redried seed after primed was lower than that of the others. The highest GP cultivar was Chunjoogoohyung and the lowest GP cultivar was Seouldego in unredried seed after primed, but Chunjoojoonggo was highest and Jungpoonwhang was the lowest cultivar in redried seed after primed. As the PEG concentration increased, the seedling length(SL) was shortened, and seed primed for 15 days was longer than other treatments. The SL of primed seed was similar to GP. The SL of washed seed after primed was longer than that of others, but that of redried seed after primed was shortest among the others. The SL of Chunjoojoonggo and Nongwoodego was longest and Seouldego was shortest among the cultivars in unredried seed after primed, but that of Chunjoogoohyung and Chunjoojoonggo was longest and Seouldego was the shortest cultivars in redried seed after primed.

These experiment were conducted to lodging-related characteristics with different seeding dates in direct seeding of flooded paddy surface in rice plant. The number of seedlings per ㎡ were from 91 to 144 plants, and seedling ratios were from ranged from 61.7% to 91.8%. Days from seeding to flowering were shortened from 5 to 10 days by the later seeding dates. Heading dates of Daecheongbyeo, Donjinbyeo, Iipumbyeo and Seoanbyeo on June 9 showed slightly elapsed on the critical stable heading time from, August 28 to 29. The culm length was effective in longer culm varieties than semidwarf varieties. The degree field lodging(degree of lodging:0∼9<9:complete lodging) in Obongbyeo and S101 with semidwarf varieties were 0.33, whereas 0.45 in Dongjinbyeo with long culm. The lodging resistant varieties, Obongbyeo and S101, showed lower values of lodging index from 1.03 to 1.15 than those of lodging susceptible varieties, Daecheongbyeo and Palgongbyeo ranged from 1.42 to 1.70. Bending moment with leaf sheath were greater in lodging resistant varieties(Obongbyeo and S101), 1510.0∼1930.4 g·cm, than those in the lodging susceptible varieties (Daecheongbyeo and Palgong-byeo), 1127.2∼1287.6 g·cm. Therefore, it is recommended to select genotype with higher value of bending moment as well as breaking moment for breeding lodging resistant varieties.

An experiment was conducted to obtain basic information for breeding sprout soybean from 133 varieties of sprout soybean cultivated in the province of Chonnam and Chonbuk. Heritabilities, genetic and environmental correlations and path coefficients of plant characters with yield were estimated. Heritabilities of number of days to flowering and 100 seed weight were very high with values of 99.7% and 94.1%, respectively. Heritabilities of hypocotyl length, number of branches, diameter of main stem and chlorophyll content were medium with values of 75.6, 63.8, 82.5 and 79.0%, respectively. Plant height, number of main stem nods, number of pods for plant and yield showed relatively high values of heritabilities with 88.6, 82.7, 84.5 and 90.1%, respectively. Yields showed highly significantly positive genetic correlations with diameter of main stem, number of branches and number of pods. It also showed significantly positive correlation with number of main stem nods and 100seed weight. The magnitude of the direct effects of plant characters on yield by path coefficient analysis was in the order of number of pods per plant, 100 seed weight, diameter of main stem, number of branches, number of main stem nods and plant height.

This study was undertaken to asses the effect of day length and seed weight on chemical composition in soybean seed. The result obtained were as followed; Longer day length caused increase in protein, but decrease in oil. As seed weight decreased, the protein content decreased, whereas the oil content was not affected by the seed weight. There were five main fatty acids; ricinoleic, palmitic, linolenic and stearic acids. Increase in day length resulted in decrease in oleic acid, but increase in linolenic acid. Oleic acid content was low in the light seeds whereas higher contents of palmitic, linolenic, and stearic acids were obtained from the lighter seeds. Positive correlation existed between stearic acid and palmitic and ricinoleic acid. However the other fatty acids showed negative correlations between each other.
