This experiment was carried out to compare the morphological traits of Korean, Chinese, Japanese and Southeast Asian(SEA) soybeans from RDA genebank. Days to flowering were ranged from 51 to 125 days with an average of 75 days. Those of China were the shortest with an average of 58 days and those of SEA were the longest with an average of 99 days. Growth days were the shortest with 94 days from China, and longest with 188 days from Korea and SEA. The 100 seed weight of soybeans was ranged from 3.4g to 46.4g, with an average 22.2g. The 100 seed weight was the lightest with an average 11.8g from SEA and the heaviest with an average 24.6g from Korea. In growth habit, over 50% of being collected from Korea, Japan and China were erect type, but 94% from SEA were intermediate type. The highest percentage of seed coat color was yellow(66.1%), followed by yellowing green(10.0%). As a result of cotyledon color in 760 black seed was 76.1% with yellow, 23.9% with green. Green cotyledon was much more in Korea(38.6%) and Japan(33.3%) than other countries. One thousand seven accessions from Korea, Japan, China and SEA were analyzed using 7 SSR markers. One hundred eighty alleles were detected with a lowest 16 at the Satt537 and a highest 35 at the Satt390. The average polymorphism information content(PIC) was 0.68, the highest with 0.7 in Japan. Gene diversity was the highest with 0.73 in China and Japan, while the lowest in SEA with 0.68.
