甘蔗新品种粤糖07-516选育及特性特征

摘要

详细阐述了早熟、高产、高糖、抗病性好的甘蔗品种粤糖07-516的选育过程,并就其农艺性状、蔗茎产量、蔗糖分、抗性等性状表现进行了综合分析.以粤糖00-236为母本,桂糖96-211(桂糖26号)为父本配制杂交组合,历经8代农艺性状、糖分和产量相关性状的选择,育成了早熟、高产、高糖、抗逆性强的甘蔗新品种粤糖07-516.通过国家区试和生产试验,结果表明,粤糖07-516蔗茎产量达108203.06 kg/hm2,含糖量达16898.59 kg/hm2.该品种适合我国蔗区大面积推广应用.%The objective of this paper was to introduce the breeding process of a new sugarcane cultivar, Yuetang07-516, and its agronomic character, including stem yield, sucrose content, and disease and abiotic stress resistance. Yuetang07-516, with early maturity, high stem yield, high sucrose content and good adversity resistance, was successfully bred using Yuetang00-236 and Guitang92-211(Guitang26) as female and male parents, after selection of 8 generations based on agronomic, sugar traits, and yield traits. It showed high sugar yield and maximum stem yield at 16898.59 kg/hm2 and 108203.06 kg/hm2 in the national regional and production test, respectively, and it is one of the most suitable sugarcane varieties in the major sugarcane growing areas.
