甘蔗新品种桂柳一号的选育及推广应用的检析

Self-Criticism on the Breeding, Popularization and Application of New Sugarcane Variety Guiliu 1

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。

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.
