'Kiyomidori' was developed at the National Agricultural Research Center for Kyushu and Okinawa Region from 1988 and was registered as 'Soybean Norin 120' in 2002. This variety was selected from the progeny derived from the cross 'Kinakomame 2' x 'Gunma Ao Daizu'. 'Kiyomidori' is a medium-maturing variety with determinate growth, broad leaflets, white flowers, and a light tawny pubescence. Its pods are dark brown at maturity. The cultivar has a medium stem and possesses resistance to lodging. 'Kiyomidori' is classified as a large-seed soybean (31. 2g / 100 seed weight). The seeds are spheroidal with a green seed coat green cotyledon, and green hila. 'Kiyomidori' is medium resistant to soybean mosaic virus (SMV) and purple seed stain. It is susceptible to soybean root necrosis, soybean cyst nematodes (SCN), and arenaria nematode (Meloidogyne arenaria). The seed yield is a little lower than that of 'Fukuyutaka' that was the leading cultivar in the western region of Japan. The protein content in the seed is 4% lower than that of 'Fukuyutaka', but sucrose content is higher than that of 'Fukuyutaka'. 'Kiyomidori' is suitable for pale green tofu processing and exhibits high productivity and adaptability in the western region of Japan. It was registered as a recommended cultivar in Miyazaki prefecture in 2004.
