A new cultivar of soybean Glycine max (L.) Merr. "Tatsumaro" was developed at the NARO Western Region Agricultural Research Center in 2014. In order to create a cultivar with resistance to seed coat mottling and seed transmission of soybean mosaic virus (SMV), plants were selected from a cross between "Sachiyutaka" and "Tanyou". "Tatsumaro" was classified into group IV on the basis of the date of maturity, which is almost the same as that of "Sachiyutaka" grown at Zentsuji, Kagawa (34° 13' 37" N, 133° 46' 39" E). "Tatsumaro" has purple flowers, gray pubescence, pointed ovate leaflets, and light brown pods at maturity. It shows a determinate growth habit and has a medium plant height. The seeds are of medium size, the color of the seed coat is yellow-ground, and that of hilum is yellow. This cultivar has astonishing resistance ; it is resistant to seed coat mottling and seed transmission of SMV. Yields of "Tatsumaro" are higher than those of "Sachiyutaka". "Tatsumaro" is adapted to cultivation in Kinki District, Japan, and it is suitable for production of soy sauce.
