摘　　要：为了验证选育的木薯新品系在广西不同生态区的生产适应性,以广西农科院经济作物研究所配合中国热带农业科学院热带作物品种资源研究所选育的E497、E333、E361、E18等4个木薯新品系进行区域试验。结果表明,与对照品种SC205相比,E497每667 m2鲜薯产量比SC205高19.22%,淀粉含量高3.6个百分点;E333每667 m2鲜薯产量比SC205高15.15%,淀粉含量高1.7个百分点;E497和E333两个品系表现出良好的生物学特性、增产效果和优良品质,在生产上有良好的推广应用前景。To verify the new strains of cassava production adaptability in different ecological zones in Guangxi,to provide a scientific basis for validation and production and promotion of the varieties.The 4 cassava new strains selective breeding like E497、E333、E361、E18,included the pilot scheme of the chair unit the regional test,and attend to the regional pilot of new cassava varieties（strains） in Guangxi in 2010.The results showed： The yield of E497 and SC205 significantly different,the fresh potato yield of E497 was 19.22% more than the check;The starch content of E497 was 29.1%,it＇s 3.6 percentage points higher than the check;The fresh potato yield of E333 was 15.15% more than the check,the starch content of E333 was 27.2%,it＇s 1.7 percentage points higher than the check.And they showed good biological characteristics,high yield and good quality,and has a good application in production.
