中文摘要：

采用大田生产模式种植,以来自同一亲本组合（粤糖97-20×ROC25）杂交后代分离产生的强宿根甘蔗品（种）系（‘云蔗06-407’、‘云蔗06-415’）和弱宿根甘蔗品（种）系（‘云蔗06-408’、‘云蔗06-416’）为材料,强宿根甘蔗品种‘新台糖22号’及宿根性一般的甘蔗品种‘新台糖10号’为对照,探讨由甘蔗种性决定的宿根影响因子与甘蔗宿根性的关系。结果表明,强宿根甘蔗较弱宿根甘蔗新植蔗蔗芽萌发速度快,萌发数多,且分蘖率高,形成的有效茎数多;强宿根甘蔗宿根发株数多,形成的有效数多于新植蔗,产量较新植蔗高。这些影响甘蔗宿根性的因子与甘蔗品种的种性密切相关。

英文摘要：

A field experiment ROC25 was conducted with a among 4 varieties, YZ06-407 containing 4 varieties （strains） derived from the same parents Yuetang97-20 x good ratoon cultivar ROC22 and a common ratoon cultivar ROC10 as control, （released in 2013） and YZ06-415 were good ratooning, and another 2 offspring YZ06-408 and YZ06-416 were poor ratooning. The relationship between the ratoon ability and impact factors decided by the varietal characters of sugarcane ratooning was explored. The results showed that the bud germination speed, number of germination, tillering rate, and number of effective stem of sugarcane of good ratooning were better than that of the sugarcane of poor ratooning. What＇s more, the amount of budding, survival rate and total yield of good ratooning sugarcane were higher than that of new planting sugarcane. All of these factors listed above were closely related to the varietal characters of sugarcane.
