甘蔗新品种桂辐98-296的选育

MUTATION BREEDING OF NEW SUGARCANE VARIETY GUIFU 98-296

桂辐98-296系采用辐射诱变技术选育而成的甘蔗新品系,全期生长快,中茎,宿根性好,抗逆性强。在广西不同蔗区生产适应性试验中,其单位面积产蔗量118.95t/hm2、含糖量16.65t/hm2,分别比当家品种ROC22增产32.98%和29.07%,差异性均达极显著水平,蔗糖分与ROC22相近。在国家第6轮甘蔗品种区域试验所有11个参试品种(系)中,其蔗产量名列第4,蔗糖含量名列第3,分别比对照种ROC16增产11.41%和12.69%,差异性达显著水平,蔗糖分比ROC16高0.11个百分点。桂辐98-296全期生长快,中茎,宿根性好,抗逆性强。

A new sugarcane variety Guifu 98-296 was selected by mutation breeding.In different sugarcane growing test areas of Guangxi,t Guifu 98-296 cane output was 118.95t /hm2,sugar output was 16.65t /hm2,and higher 32.98% and 29.07% respectively than those of ROC22 which was main variety in Guangxi,and the differences between the two were very significant.At the sixth national test for cane growing areas,Guifu 98-296 was the fourth in cane yield,and the third in sugar yield among all eleven participated varieties.The cane yield and sugar yield were significant 11.41% and 12.6% higher than control variety of ROC16 respectively,and the sugar percentage was 0.11% higher than ROC16.Guifu 98-296 grows quickly with middle stalks,strong resistance to insect and disease,good ratoon performance,and is suitable for growing in the drought and slope upland of Guangxi Province.
