高糖高产甘蔗新品种粤糖07-817的选育研究

粤糖07-817是广东省生物工程研究所(广州甘蔗糖业研究所)以粤农73-204作母本,ROC22作父本进行有性杂交,经多年选育而成的甘蔗新品种,2016年通过广东省农作物品种审定委员会审定。多年多点试验研究表明,粤糖07-817出苗率高,分蘖力强,有效茎多,中大茎,蔗茎均匀,脱叶性好,抗倒伏;宿根发株率高,宿根性强;早熟、高产、高糖、综合性状好。2009~2014年品种选育试验和广东省区域试验6年新植5年宿根蔗茎产量达129340 kg/hm~2,含糖量达20103 kg/hm~2,分别比ROC16(CK1)增产36623 kg/hm~2和5971 kg/hm~2,比ROC22(CK2)增产10256 kg/hm~2和1854 kg/hm~2。

Breeding of Sugarcane Variety Yuetang 07-817 with High Sugar Content and High Yield

Yuetang 07-817 was selected from cross Yuenong 73-204 (female parent) × ROC22 (male parent) at Guangdong Provincial Bioengineering Institute (Guangzhou Sugarcane Industry Research Institute). It was approved as a new variety by the Guangdong Crop Variety Approval Committee in September 2016. Multiple-year and multiple-location evaluations showed that Yuetang 07-817 had the following good characteristics: high emergence rate; strong tillering ability with more millable canes, mid to large size, and uniform stalks; easy foliar defoliating at maturity; resistance to lodging; good ratooning ability with high germination rate; early maturity; high sugar content; and high and stable yield. During 2009~2014, the average cane yield of Yuetang 07-817 from variety comparison and Guangdong provincial trials involving six plant crop years and five ratoon crop years was 129340 kg/hm2, which was 36623 kg/hm2 and 10256 kg/hm2 higher than the that of the check variety ROC16 (CK1) and ROC22 (CK2), respectively. The average sugar content was 20103 kg/hm2, which was also 5971 kg/hm2 and 1854 kg/hm2 higher than that of the check variety ROC16 (CK1) and ROC22(CK2).
