Agronomic characteristics and chemical composition of sprout soybean varieties

Improvement of sprout soybeans could be accomplished by maintenance and collection of varieties which have characteristics of small seed, disease resistance and high yielding ability. This research was conducted to investigate morphological and ecological characters for 102 sprout soybean varieties collected in Chonnam and Chonbuk area, and donated by Sprout Soybean Association and Genetic Engineering Research Institute. The sprout soybean collections contained 85% purple flower color, 76% ring-type leaf, 68% brown trichome, 57% elliptical-type seed, 69% yellow seed color and 44% brown hilum color. Days to flowering ranged from 53 to 79 days and growth duration averaged 137 days, with the range of 119~149 days. Stem length ranged from 52㎝ to 165㎝ and 100-seed weight distributed into 4.9~13.3g. The grain yield revealed large range of 0.53~4.18MT/ha. Crude protein and lipid contents was ranged 35.8~48.7% (average 40.9%), and 19.1~’21.2% (average 20.1%), respectively. Correlation coefficients between grain yield and pod numbers was significantly positive, while that between 100-seed weight and pod numbers was significantly nagative. Crude protein contents was significantly associated with growth duration but negatively correlated with 100-seed weight and yield. Crude lipid contents was negatively correlated with growth duration but positively associated with 100-seed weight.
