2008年以华南5号为母本，华南205为父本，进行木薯品种间杂交，以选育高产、高淀粉、高抗逆性木薯新品种。当年获得杂交种子936颗，经多代系统选育，于2013年获得综合性状优良的新品系桂垦09－26，鲜薯产量达48.64 t／hm2，比对照华南205增产90.43％；淀粉含量达30.0％，与华南205相近。综合各种农艺性状表现，桂垦09－26可以进一步参加区域性试验和生产性试验。%In 2008,using Huanan No.5 as female parent,205 as male parent,the intervarietal crossing was conducted a-mong cassava varieties in order to breed high-yielding,high-starch,high resistance of new varieties of cassava,and 936 hybrid seeds was then got.After multi-generation breeding system,a new new lines Guiken 09-26 with better com-prehensive quality traits was found in 2013.The fresh potato production of Guiken 09 -26 reached 48.64 t/hm2 ,which was 90.43% more than that of the control Hunan 205;the starch content was 30.0%,which was similar to that of Hua-nan 205 .Considering the comprehensive variety of agronomic traits,Guiken 09-26 can be used in further regional testing and production test.
