Expression of new germplasm is very important in breeding program because the characters are the reflection of the genes and the environment. The objective of this study is to evaluate the expression of agronomic characters of 20 Korean soybean varieties in Indonesia. The experiment was conducted at greenhouse of the Indonesian Legumes and Tuber Crops Research Institute in Malang during May to August 2012. The materials were consisted of 20 Korean soybean varieties, and four Indonesian soybean varieties as check. The experimental design was randomized completely block with three replications. Result showed that there were significant differences among germplasm for the characters of days to flowering, days to maturity, plant height, number of branches per plant, number of reproductive nodes per plant, number of filled pods per plant, number of seeds per plant, seed yield per plant, and 100-seed weight, but there were no differences on number of unfilled pods per plant. Usually, all of Korean varieties have shorter plant height than the Indonesian soybean varieties. Based on seed yield per plant, the best perfomance were showed by Daewonkong, Detam 1, Jangmikong, and Songhakkong, i.e. 12.8 g, 11.6 g, 11.4 g, and 11.3 g per plant respectively. The seed yields of these varieties were higher than the Indonesian popular variety of Anjasmoro (8.8 g).
