| Abstract: | Objective] This study aimed to provide good commercial sugarcane vari-eties for Guangxi sugar industry. Method] After regional and production test with sugarcane plants in two years and ratoons in one year, a new sugarcane variety GT39 characterized by good ratooning ability, high yield and sugar-content, and large stalks was bred by sexual hybridization between Yuetang 93/159 （male parent） and ROC22 （female parent） through the ＂Five Nurseries＂ breeding procedure, which was approved by Guangxi Crop Variety Approval Committee in March 2012. Re-sults] The results of regional test showed that the average cane yield of GT39 was 97.2 t/hm2, 5.3% and 11.2% higher than the control ROC22 and ROC16, respective-ly; the average sucrose content was 14.07% from Nov. to next Feb, 0.05% higher than ROC22 and 0.02% lower than ROC16; the average sucrose content was 14.02 t/hm2, 9.1% and 10.4% higher than ROC22 and ROC16, respectively. Conclusion] GT39 was suited to be planted in both dry land and paddy fields with medium-level or above fertility in Guangxi sugarcane-producing area. |
