Good storability and sprouting. Precocious, generally 25-30 days to produce potatoes, 120-130 days to harvest. The drying rate was 29.25%, the taste score was 79.7, slightly lower than the control, the starch rate was 18.07%, and the vitamin C content was 22.17 mg / 100 g. Identified by the Institute of Agricultural Sciences of Puning City, Guangdong Province, resistance to potato blast in the field, indoor inoculation identified as Ⅰ group high susceptibility, Ⅱ group susceptibility, moderate susceptibility to vine disease.
Yield performance: in the national regional trials of sweet potato varieties in southern China in 1999 and 2000, the average yield of fresh potato per mu in two years was 2017 kg, which was 77.44% higher than that of Guangshu 88-70, reaching a very significant level. In 2001, the production experiment of Guangxi Maize Institute showed that the yield of fresh potato per mu was 1839.5 kg, which was 22.2% higher than that of the control Baise high quality variety, the dry matter rate was 28.5%, and the yield of dry potato per mu was 524.3 kg, 23.5% higher than that of the control species. In the production test in Chaozhou City, Guangdong Province, the yield of fresh potato per mu was 3432 kg. Compared with Pushu 6, the yield of dry potato per mu was 30.7%, and the yield of dry potato per mu was 1053.5 kg, 33.6% higher than that of the control.
