A high-starch sweet potato variety,‘Rongshu819',was newly developed from ‘Jinshan57'by open pollination in 2008.It was subjected to the regional test on new varieties and a production trial in Fujian from 2011 to 2013.The results showed that ‘Rongshu819'had a higher dry matter content and significantly higher root starch yield than ‘Jinshan57'(CK).Specifically,the dry matter of ‘Rongshu 819'was 29.95%,which was19.85% higher than that of CK,and the root starch was 19.70%,which was 28.09% more than that of CK.In addition,this new variety was judged to be better in table quality than CK,as well as moderately resistant to fusarium wilt,desirable on storage performance and highly acceptable in germination ability.It was,subsequently,certificated by Fujian Committee for Crop Variety Registration in 2014.
