Abstract:

In order to breed a new dual-purpose sweet potato variety with high yield and quality, which can be used for both fresh food and starch processing, ‘Rongshu 910’ was bred by group hybridization with ‘Rongshu 756’ as female parent. The variety was involved in the regional test and production test of new sweet potato varieties in Fujian Province from 2014 to 2016. The results of multi-point test showed that the fresh potato yield, dry potato yield and starch yield of the variety were significantly higher than those of the control variety ‘Jinshan 57’; and the variety had high yield stability, good taste quality, moderately resistance to fusarium wilt and good storage performance. ‘Rongshu 910’ passed the national registration of non-major crop varieties in 2019 [GPD sweet potato (2019) 350022], obtained the right of new plant varieties in 2022 (CNA20193211.5), and was listed as the leading variety in Fujian Province in 2024.
