'Yeseumi', a new sweetpotato variety resistant to fusarium wilt, was developed for table use by Bioenergy Crop Research Institute, National Institute of Crop Science (NICS), Rural Development Administration (RDA) in 2013. 'Yeseumi' was derived from the cross between 'Mokpo34' and 'Singeonmi' resistant to fusarium wilt in 2005. The seedling and line selections were conducted from 2006 to 2008. Preliminary and advanced yield trials were carried out from 2009 to 2010. The regional yield trials were performed at five locations from 2011 to 2013. 'Yeseumi' has three-lobed leaf, and its leaves, stems, petioles, and nodes are green. Storage root of 'Yeseumi' has an elliptical shape, red skin, and light orange flesh. 'Yeseumi' was highly resistant to fusarium wilt and susceptible to root-knot nematode. Dry matter content was 25.4%, and texture of steamed storage root was intermediate. Total sugar contents of raw and steamed storage root of 'Yeseumi' were higher than those of 'Yulmi'. β-carotene content of 'Yeseumi' was 15.7 mg/100 g DW. Yield of marketable storage root over 50 g of 'Yeseumi' was 32.5 MT/ha under the early season culture, which was 97% higher than that of 'Yulmi'. The number of marketable storage roots per plant was 2.8 and the average weight of marketable storage root was 143 g under the normal and late season culture. Marketable storage root yield of 'Yeseumi' was 23.9 MT/ha under the normal and late season culture, which was 42% higher than that of 'Yulmi'. (Registration No. 5848).
