摘　　要：中糖3号是中国热带农业科学院热带生物技术研究所以粤糖99-66为母本,新台糖28号为父本杂交选育的甘蔗新品种,于2020年9月通过农业农村部非主要农作物品种登记。在1新2宿的品种比较试验中,中糖3号平均蔗茎产量为130.14 t/hm^(2),较对照品种新台糖22号增产16.03%;平均蔗糖分为14.79%,较新台糖22号增加1.01个百分点;产糖量为19.34 t/hm^(2),较新台糖22号增产24.05%;平均纤维分为10.85%,较新台糖22号提高了1.12个百分点。在机械收获性方面,中糖3号机械收获3季平均损失率为4.34%,较新台糖22号损失率5.39%,减少了19.48%;平均含杂率为6.12%,较新台糖22号含杂率7.13%,减少了14.17%。综合多年多点试验表明:中糖3号为中晚熟品种,丰产高糖、出苗快,分蘖力较强、宿根发株数多,抗黑穗病、中抗花叶病,同时兼具蔗茎直立均匀、内容充实、不易倒伏和风折、易脱叶、适宜机械化收获作业等优良农艺性状,具备较好的商业品种推广种植潜力。Zhongtang3 is a new sugarcane variety that was bred by hybridization from Yuetang99-66×ROC28 by Institute of Tropical Bioscience and Biotechnology,CATAS.It was registered as the non-major crop variety by the Ministry of Agriculture and Rural Affairs in September 2020.In the cultivar performance test of one-year new planting and two-year recurrent root,the average sugarcane yield of Zhongtang3 was 130.14 t/hm^(2),16.03% higher than that of the control ROC22.The average sucrose content was 14.79%,1.01 percent point higher than that of control ROC22.The average sugar yield was 19.34 t/hm^(2),24.05% higher than that of the control ROC22.And the average fiber content was 10.85%,1.12 percent point higher than that of control ROC22.In terms of the mechanized harvesting performance,the average loss rate in 3 years Zhongtang3 was 4.34% and the control ROC22 was 5.39%.The loss rate decreased by 19.48%.The average impurity rate in 3 years Zhongtang3 was 6.12% and the control ROC22 was 7.13%.The impurity rate decreased by 14.17%.Comprehensive multiple-year and multiple-site experiments had shown that Zhongtang3 was a middle-late variety with high yields and high sugar content.The newly planted seedlings were emergence fast and tillering more while the root plant had a high bud rate.It shows resistance to smut and moderate resistance to mosaic disease.The stem is thick,upright and uniform with full content and not easy to fall down and wind damaged.Zhongtang3 has excellent agronomic traits such as better defoliation and mechanized harvesting performance,and good potential for commercial cultivation.
