조기재배용 분질고구마 ‘진다미’

초록

In 2022, Jindami was developed as an early maturing mealy sweet potato variety. It was derived from a cross between Dahomi (IT309420) with early maturity and Jinyulmi (IT327287) with early maturity and good palatability. The storage roots of Jindami have a light-purple skin, yellow flesh, and a reverse-ovate shape. When steamed, Jindami storage roots exhibit a mealy texture and are tenderer than those of the check variety, Jinyulmi. The sugar content of steamed Jindami storage roots was 25.4 mg/100 g on a dry weight basis, which was 6.0% higher than that of Jinyulmi. The marketable yield of Jindami storage roots was 28.6 t/ha in the early-season production, which was 19.2% higher than that of Jinyulmi with high yield in the early-season production. Jindami is resistant to root-knot nematode and Fusarium wilt. Jindami is expected to contribute to an increased income for sweet potato-growers as it has good palatability and can be shipped at a time when the market price is high owing to its high yield in the early-season production.
