摘　　要：木薯品种新选048是广西大学木薯课题组从木薯种质资源ZM93-16的自然变异群体中选出优良单株,再经过系统选育和定向选择育成的木薯新品种。该品种株型好,不分枝,茎杆节密,种茎发芽快,长势旺,结薯多,薯块大,结薯集中,容易收获,适应强,丰产性好。一般产鲜薯45000～60000kg/hm2,高产的达75000kg,鲜薯淀粉含量28%～30%。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 characteristic with seed stem germinating rapidly; leaf and stem growing vigorously. It was harvested more easily than other cuhivars 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 45 000-60 000 kg/hm：, the highest yield was more than 75 000 kg/hm^2. The change of starch content in the tu- berous root was from 28% to 30%.
