Summary on the agronomic and yield perfomance of new sugarcane variety Guifu 98-296 in Guangxi regional trial

Guifu 98-296, selected from the mutants of donor clone after it was exposed to physical and chemical mutagenic agents, is a new variety which is adapted to those cane fields on dry slope upland. In the regional trial of Guangxi, the average cane and sugar yield of Guifu 98-296 increased by 18.24% and 20.89% over the leading variety要要ROC22 (CK1), and meanwhile increased by 24.86% and 26.98% over the ROC16 (CK2) respectively. In the production demonstration of Guangxi, its cane yield increased by 3.98% and 16.13% over the ROC22(CK1, 99.63 t/hm2) and ROC16 (CK2, 89.22 t/hm2). In the high yield demonstration of Guangxi, its cane yield increased by 31.49% over the ROC22 at Pingxiang test spot, and its average cane and sugar yield increased by 22.94% and 23.54% over the ROC22 respectively at Baise test spot.
