Studies on the performances characteristics of collected native sprout soybean 1. Variation of characteristics in collected native sprout soybean

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.
