'Kinusayaka' was registered as 'Soybean Norin 130' by the Ministry of Agriculture, Forestry and Fisheries. Japan, and adopted as a recommended variety by Miyagi Prefecture. 'Kinusayaka' was derived from the cross 'Karikei508' x 'Karikou0459F1' made in 1993. 'Karikei508' is a breeding line with three lipoxygenase isozymes deletion. 'Karikou0459F1' was derived from the cross 'A-b (F)-A0' x 'Suzuyutaka'. 'A-b(F)-A0' lacks Group A acetyl saponin. 'Kinusayaka' has a determinate growth habit, white flowers, gray pubescence, brown pods, and yellow seeds with a yellow hilum. It averaged a 23rd October maturation date, 79cm plant height a 300kg/10a seed yield, 23.5g 100-seed weight 40.9% protein content and 19.8% oil content at the Kariwano Branch (39 deg. N Lat), NARCT. 'Kinusayaka' has resistance to soybean mosaic virus, but not to soybean cyst nematode. 'Kinusayaka' lacks three lipoxygenase isozymes and Group A acetyl saponin. 'Kinusayaka' is highly suitable for processing soy milk and tofu, and those made from it have a less beany and astringent flavor.
