【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。更多还原

【Abstract】 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.更多还原
