Abstract: Cassava cultivar Xinxuan 048 is a new one which bred by cassava project group of Agricultural College, Guanxi University with system breeding method from natural variation plant of cassava resource ZM93-16. The cultivar had a good plant form with no branch and dense stem note; and a good growth characteristics with seed stem germinating rapidly; leaf and stem growing vigorously. It was harvested more easily than other cultivars because its root tubers grew densely in the surface soil. It was shown in many experiments that the yields of Xinxuan 048 were higher than those of other cultivars. Generally, the yields of Xinxuan 048 were 45000-60000kg/hm2, the highest yield was more than 75000 kg/hm2. The change of starch content in the tuberous root was from 28 percent to30 percent.
