The study developed a new fresh-eating sweet potato variety Guishu No. 13 and established its virus-free seedling breeding technology system to meet the market demand for fresh-eating sweet potato varieties and healthy seedlings. Guishu No. 13 was bred from seeds by open pollinated using Guizhu No. 10 as mother. The variety has purple red skin, orange yellow flesh, and a high rate of medium to large storage roots. The content of β-carotene, protein and reducing sugar was 1790 mg/100 g, 1860 mg/100 g and 1200 mg/100 g, respectively. In the production experiment, the starch storage roots yield was 29 786.40 kg/hm2 and starch yield was 4675.10 kg/hm2, which increased by 5.52% and 17.52% respectively compared to Guishu No. 2 (CK). Guishu No. 13 has moderate resistance to Fusarium wilt, black rot, and stem nematode. The best culture medium for callus differentiation and germination rate of Guishu No. 13 was MS+0.10 mg/L NAA+1 mg/L 6-BA and MS+0.20 mg/L NAA+2 mg/L 6-BA, respectively. Guishu No. 13 has good yield and stability, high fresh storage root yield, and the establishment of a virus-free breeding system would lay the foundation for the development and application of the Guishu No. 13.
