Abstract: A new sweetpotato cultivar ‘Rongshu No.153’ with high yield and good quality was bred from female parent ‘jinshan No.57’ with early maturity, high yield, good quality, excellent characteristics and male parental material ‘B1’ with high dry matter content, high disease resistance by directed hybridization and multipoint identification. The morphological characteristics, agronomic characteristics, quality characteristics, disease resistance, productivity and adaptability of ‘Rongshu No.153’ was experimental studied, The results indicated that it had medium sprouting capacity and steady vigor during all growth period. In Fujian Provincal Sweetpotato Regional Trial (2013-2014), the average yield of fresh tuberous root of ‘Rongshu No.153’was 41.3873 t/hm2 and 5.20 percentage point higher than ‘jinshan No.57’ (CK); The average dry matter rate was 27.68% and 1.45 percentage point higher than ‘jinshan No.57’; The average starch rate was 17.72% and 1.26 percentage point higher than ‘jinshan No.57’; The test value of cooked taste was 80.2 and 0.2 percentage point higher than ‘jinshan No.57’; The test value of extrinsic feature was 80.5 and 0.5 percentage point higher than ‘jinshan No.57’; It showed moderate resistance to Fusarium oxysporum and resistance to Ralstonia solanacearum wilt. The storability of tuberous root was strong. It was approved by Fujian Provincial Crop Varieties Appraisal Committee in 2016(the approval number: Minshenshu2016003), and it is suitable for growingSinSwideSareas for fresh-eating or processing.
