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.
