34个国外引进甘蔗种质三年宿根性产质量评价

Evaluation on Yield and Sucrose Content to Foreign Ratoon Sugarcanes

对34份国外引进甘蔗种质3年宿根的表现,根据糖分和产量结果从中评价出28个表现优异的甘蔗种质。其中,宿根性强、高产、高糖种质7个,占总数的20.59%;宿根性强、高产种质12个,占总数的35.29%;高糖种质9个,占总数的26.47%,为进一步提供生产和育种利用。

34 foreign sugarcane varieties were selected from national sugarcane germplasm nurse in order to evaluate their third year ratoon. According to evaluating sucrose content and yield of sugarcanes, the result showed 28 varieties from the total experimental varieties were excellent in yield and sucrose content. 7 sugarcane varieties from the 28 varieties possess strong ratoon, high yield and high sucrose, taking up 20.59%; and 12 belong to strong ratoon and high yield, about 35.29%; and 9 sugarcane varieties were high sucrose, about 26.47%. These excellent varieties could be tltilized as improving quality of sugarcane varieties.
