摘　　要：‘桂糖58号’是以‘粤糖85-177’为母本、‘CP81-1254’为父本通过杂交育种方法选育出的甘蔗新品种。在广西甘蔗品种区域试验中,‘桂糖58号’1新2宿平均甘蔗产量为108.9 t/hm^(2),比对照‘新台糖22号’增产29.5%;平均甘蔗蔗糖分为14.94%,比对照‘新台糖22号’高0.55个百分点;平均含糖量为14.5 t/hm^(2),比对照‘新台糖22号’增加42.2%。‘桂糖58号’具有高产、稳产、高糖、宿根性强、易脱叶等优良特性,适宜在广西各蔗区种植。Guitang 58 was bred by hybridization of Yuetang 85-177 as female parent and CP81-1254 as male parent.The results from 1-year plant and 2-year ratoon crops in Guangxi sugarcane variety regional trials showed that the average cane yield of Guitang 58 was 108.9 t/hm^(2),29.5%higher than CK("ROC"22);The average sucrose content of Guitang 58 was 14.94%,0.55%(absolute value)higher than CK("ROC"22);The average sugar yield of Guitang 58 was 14.5 t/hm^(2),42.2%higher than CK("ROC"22).Guitang 58 performed high yield,stable yield,high sucrose content,strong ratoon ability and self-trashing,and is suitable for planting in sugarcane area of Guangxi.
