A new soybean [Glycine max (L.) Merr.] cultivar "Aomarukun", registered as "Soybean Norin 123" in 2002, was developed at the National Agricultural Research Center of the Tohoku Region. In order to develop a cultivar with a green cotyledon, early maturity, and high compatibility for mechanical management, plants were selected from a cross between a green-cotyledon indigenous Korean variety "Aka ao D165" and "Tachiyutaka". The date of maturity of "Aomarukun" is earlier than that of "Suzukari" at Nishisenboku, Akita (Latitude 39° 32' N, Longitude 140° 22' E). The cultivar was classified into group III based on the date of maturity. "Aomarukun" has purple flowers, gray pubescence, broad leaflets, and brown pods at maturity. It has a medium stem (ca. 65-85 ㎝), and shows a determinate growth type and high lodging resistance. Green cotyledon, pale green seed coat and green hila are the characteristics of seeds of "Aomarukun". "Aomarukun" is suitable for pale green Tofu production. It is highly compatible with the central part of Tohoku district. "Aomarukun" was released as a new recommended cultivar from Iwate prefecture in 2002.
