Longshu 14 was a sweet potato variety bred by crossing Zheshu 60-2 and Guangshu 87. It has passed the national registration in 2008 and the provincial registrations in 2013. The fresh yield of the variety was 28.16 -43.80 t · hm-2 ,which was 82.10% -103.90% of that of the reference varieties (CK) ,Jinshan 57 or Guangshu 87. Its dry yield was 8.05-11.30 t · hm -2 ,which was 96.50% -109.10% of that of CK .Its starch production was 5.21-7.51 t · hm -2 ,which was 98.80% -110.83% of CK′s .Its tuber dry matter and starch contents were higher than CK ,approximately 30% and 19% ,respectively .And ,most of its major nutrients were in higher concentrations than those in Jinshan 57. This newly bred variety also exhibited a high resistance to fusarium wilt and moderately resistant to bacterial wilt .It had a red skin ,yellowish flesh ,and appealing appearance ,which were considered to be of high commercial value .It was recommended to plant 52 500 to 60 000 plants per hectare ,allow a grow th period of longer than 140 days ,and fertilize normally with an added late stage topdressing .
