영문 초록

Soybean [Glycine max (L.) Merr.] is an excellent source of protein, oil, carbohydrates, and many other bioactive ingredients. However, its raw mature seeds also contain several antinutritional components. The newly developed soybean cultivar ‘Hayoung’ has large yellow seeds and a low stachyose content, and is free of lipoxygenase, Kunitz trypsin inhibitor (KTI), and 7S α’-subunit proteins. ‘Hayoung’ was selected from the population derived from a cross between the intermediate parent (F4-4) and the breeding line (15G1). It has purple flowers, tawny pubescence, a determinate growth habit, and light-yellow pods at maturity. The seed of the cultivar has a yellow hilum and yellow seed coat color. The dry weight seed protein and oil content were 37.9 and 16.0%, respectively. The stachyose content was 3.1 g/kg, which was much lower than 12.7 g/kg of the check cultivar, ‘Daewon’. ‘Hayoung’ has shown resistance to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and bacterial pustule. ‘Hayoung’ matured on 22 October with a plant height of 56 cm and a 100-seed weight of 32.3 g. The average yield of the cultivar was 3.12 (Ton/ha), based on regional yield trials in 2018 at four locations. ‘Hayoung’ has been registered as a soybean cultivar (registration number: 8625, registration date: June 08, 2021) by the Korea Seed & Variety Service, Republic of Korea.
