Soybean varieties in Korea are generally classified into three types, namely, bean sprout (and high oil), grain (high yielding general purpose), and vegetable (used for mixed boiling and as green vegetables). Varietal characteristics in each type were investigated using 72 varieties for bean sprout, 115 for grain and 59 for vegetable types. The results obtained are as follows: 1. One hundred seeds weight was 13±2.5g in the bean sprout type, 22±3.3g in the grain type and in vegetable type it was 22±6.8g. Significant difference was observed between bean sprout and grain types. Variation in 100 seeds weight was larger among vegetable type than the other two types (Fig. 2). 2. According to the days from seeding to first flower anthesis, it seemed that in Korean soybean varieties intermediate type was the most, followed in descending order by autumn type and summer type. In the bean sprout type, frequency of autumn type varieties was higher than in vegetable and grain types (Table 1). 3. Based on the increase in number of nodes on the main stem after first flower anthesis, about 96% of grain type was determinate, while about 10% in each of bean sprout and vegetable types was indeterminate (Table 2).
