摘要
粤糖辐90-15是广州甘蔗糖业研究所以粤糖85-177为供体,用Co60 7000 R辐照供体种芽,从其突变体中选育而成。1993～1997年所内5年新植、宿根试验结果,粤糖辐90-15单位面积平均产蔗量、含糖量、平均蔗糖分分别较供体粤糖85-177提高0.9％、4.6％和0.47％（绝对值,下同）,田间孕穗率较供体降低24.69％。1997～1999年广东、广西、湖南区域试验结果,新植粤糖辐90-15单位面积平均产蔗量、含糖量分别较CK提高16.8％和8.9％,平均蔗糖分则降低了0.78％;宿根单位面积平均产蔗量、含糖量、平均蔗糖分分别比CK提高11.4％、31.8％和2.11％。该品种适宜水田和水肥条件好的旱坡地种植。
YTF 90-15 is a radiation mutation variety selected from the donor buds of YT 85-177 by radiation with Y -ray (Co60) at 7000 R. Compared with donor YT85-177, YTF90-15 increases cane yield by 0.9%, sugar yield by 4.6%, average sucrose content by 0.47% (absolute value), and reduces sugarcane boot rate in the field by 24.69% during a five years' trial in new-plant and ratoon from 1993 to 1997 in Guangzhou Sugarcane Trial Station GZSIRI. Compared with check variety, YTF 90-15 increases 6.8% in cane yield, 8.9% in sugar yield and reduces 0.78% in average sucrose content in new-plant cane; increases 11.4% in cane yield, 31.8% in sugar yield, 2.11% in average sucrose content in ratoon cane during a three years' regional trial from 1997 to 1999 in Guangdong, Guangxi and Hunan province. It is adaptable to growing both in paddy soil and upland with fertile soil.
