桂柳一号(柳城03-182)，亲系：CP72-1210×ROC22，由柳城县甘蔗研究中心选育，于2010年5月通过广西农作物品种审定。该品种产量与 ROC22相当，生长势强，中大茎、特早熟，蔗糖分高且稳定，宿根性强、抗旱和耐寒性强，脱叶性好。至2012年最高推广面积达到5800 hm2；2013年种植面积下降至2000 hm2。经检讨，该品种对芽后除草剂较为敏感和中感黑穗病的种性缺陷成为推广应用的主要障碍。
桂柳一號(柳城03-182)，親繫：CP72-1210×ROC22，由柳城縣甘蔗研究中心選育，于2010年5月通過廣西農作物品種審定。該品種產量與 ROC22相噹，生長勢彊，中大莖、特早熟，蔗糖分高且穩定，宿根性彊、抗旱和耐寒性彊，脫葉性好。至2012年最高推廣麵積達到5800 hm2；2013年種植麵積下降至2000 hm2。經檢討，該品種對芽後除草劑較為敏感和中感黑穗病的種性缺陷成為推廣應用的主要障礙。

Guiliu 1 (Liucheng03/182), whose parent are CP72-1210×ROC22, was selected and breed by Sugarcane Research Center of Liucheng County. It was approved by Guangxi Crop Variety Approval Committee in May 2010. Its yield is equivalent to ROC22, with strong growth, medium to big stalk size, especially-early maturing, high and stable sugar content, strong ratoon ability, strong drought and cold resistance, good defoliation. The extended area reached a maximum of 5800 hm2 in year 2010 and decreased to 2000 hm2 in 2013. After self-criticism and analysis, its defects of sensitivity to post-emergent herbicides and medium susceptibility to smut became main obstacles for popularization and application.
