"Hatamusume" is classified into group IV based on the date of maturity at Kariwano, Akita (latitude 39°32' N, longitude 140°22' E). It has purple flowers, gray pubescence and brown pods at maturity. It has a medium stem height with determinate growth habit. It is resistant to both SMV strains, A, B, C and D, and SCN race 3. The seeds of "Hatamusume" are medium-sized, with an only slightly wrinkled seed appearance and yellowish white seed coats with yellow hila. "Hatamusume" is suitable for tofu and natto processing". Hatamusume" shows high productivity and adaptability in the mid-range and southern areas of Tohoku district.
