A new cassava variety Gui 1289 with excellent comprehensive traits such as good plant type, high yield, high starch, and wide adaptability was bred by systematic breeding procedures using SC5 as the maternal parent and SC205 as the paternal parent. The average yield of fresh roots for this variety was 49.92 t/hm2 in regional test over the years, which was 24.21% higher than that of the control NZ 199. The average yield of fresh roots was 50.76 t/hm2 in production test, which was 21.26% higher than that of NZ 199. The average starch content in regional test over the years was 30.22 g/100 g, an increase of 5.42 g/100 g compared to NZ 199. The average starch content in production test over the years was 29.96 g/100 g, an increase of 5.57 g/100 g compared to NZ 199. The field test of Tetranychus cinnabarinus showed moderate resistance. It is suitable for popularization in cassava planting areas such as Guangxi, Guangdong, Hainan and Jiangxi, and so on. This study would provide a new germplasm resource for achieving high-quality production of cassava in China, which is of great significance to increase the income of the farmers and increase the efficiency of enterprises
