摘要
文章详细阐述了高产、高糖、抗病性好、抗旱性强的甘蔗品种粤糖02-305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综合分析。以粤农73-204为母本,CP85-384和CP92-624为混合父本配制杂交组合,历经9代农艺性状、糖分和产量相关性状的选择,育成了高产、高糖、抗逆性强的甘蔗新品种粤糖02-305。国家区试和生产试验结果表明,粤糖02-305蔗茎产量达104080.95 kg/hm2,含糖量达15050.11 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, Yuetang 02-305, and its agronomic character, stem yield, sucrose content, and disease and abiotic stress resistance. Yuetang 02-305, with high stem yield, high sucrose content and good adversity resistance was successfully bred using Yuenong73-204 and CP85-384 or CP92-624 as female and male parents after 9 generations＇ selection based on agronomic, sugar traits, and yield traits. It exhibited the high sugar yield and maximum stem yield at 15050.11 kg/hm2 and 104080.95 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.
