‘Hogammi’, a Sweetpotato Variety for Table Use

‘Hogammi’ was developed as a sweetpotato variety with β-carotene content and excellent palatability in 2015. It was derived by crossing ‘AB95007-2’, which has good shape and storage root yield, and ‘Annoimo’, which has light orange flesh and good palatability. ‘Hogammi’ had storage roots with long elliptical shape, red skin, and light orange flesh. The texture of the steamed storage root of ‘Hogammi’ was intermediate or slightly moist, and it was more tender than that of ‘Yulmi’. The soluble solid content of the steamed storage roots of ‘Hogammi’ was 29.7 °Brix, which was 10.8% higher than that of ‘Yulmi’. The palatability of the steamed storage roots of ‘Hogammi’ was better than that of ‘Yulmi’. The β-carotene content of the storage roots of ‘Hogammi’ was 9.8 mg/100 g dry weight. ‘Hogammi’ was moderately resistant to Fusarium wilt and root-knot nematode. In ‘Hogammi’, the number of marketable storage roots per plant and the average weight of marketable storage root were 3.4 and 133 g under culture in the normal season, respectively. The marketable storage root yield of ‘Hogammi’ was 24.1 MT/ha under culture in the normal season, which was 4% higher than that of ‘Yulmi’. The yield of marketable storage root over 50 g of ‘Hogammi’ was 14.5 MT/ha under culture in the early season, which was 39.8% lower than that under culture in the normal season. ‘Hogammi’ was more suitable for culture in the normal season (Registration No. 6466).
