强宿根早熟高糖甘蔗新品种闽糖11610的选育及种性分析

Breeding and Characterization of Early-maturing, Ratoon-suitable, High-sucrose Sugarcane Mintang 11610

  • 摘要:
    目的 培育丰产高糖、宿根性好、抗逆性强的甘蔗新品种,为甘蔗糖业可持续发展提供良种支持。
    方法 以高产、抗逆性强的粤农73-204为母本、抗病性强、高产稳产、早熟高糖CP72-1210为父本进行甘蔗有性杂交育种,采用甘蔗常规杂交育种程序“五圃制”育成甘蔗新品种闽糖11610,通过品种比较试验和多年多点区域试验综合调查甘蔗新品种闽糖11610的形态特征和种性特性。
    结果 闽糖11610植株直立,中大茎;出苗好,分蘖力强,成茎率高;抗倒伏性强,宿根性好。2015—2020年多年多点试验平均蔗茎产量为152.998 t·hm−2,比对照(新台糖22,下同)增产13.89%;蔗糖分16.31%,比对照增加1.44%(绝对值);平均含糖量为24.946 t·hm−2,比对照增产24.90%,宿根栽培蔗茎产量166.268 t·hm−2,比对照增产28.23%,平均蔗糖分16.79%,比对照增加1.07%(绝对值),含糖量27.919 t·hm−2,增糖36.99%。闽糖11610于2023年12月通过国家非主要农作物品种登记,登记编号GPD甘蔗(2023)350009。
    结论 闽糖11610宿根性好、早熟、丰产高糖,稳定性分析表明该品种丰产稳产性能优于对照,适应性较广。

     

    Abstract:
    Objective  A new sugarcane variety of high yield, high sucrose content, strong ratooning ability, and superb stress resistance was bred.
    Method  A sexual hybridization breeding program, "Five-nursery System", was applied using Yuenong 73-204 as the female parent and CP72-1210 as the male parent for the breeding. Morphology and production of the new sugarcane variety were evaluated at official trials.
    Results  The Mintang 11610 plant had a medium to large stem and superb performances on seedling emergence, tillering ability, stalk formation, lodging resistance, and ratooning ability. In the 2015–2020 trials, it showed a convincing 13.89% higher average cane yield of 152.998 t·hm−2, 1.44% higher sucrose content (in absolute value) of 16.31%, 24.90% higher crop sugar yield of 24.946 t·hm−2, 28.23% higher perennial root cultivated cane yield of 166.268 t·hm−2, 1.07% higher sucrose content (in absolute value) of 16.79%, and 36.99% higher sugar yield of 27.919 t·hm−2 than those of control. It was officially approved a national non-major crop variety in December 2023 with the registration number of “GPD Sugarcane (2023) 350009”.
    Conclusion  Mintang 11610 was an officially certified early-maturing, high-yield, high-sucrose, premium ratooning sugarcane with broad adaptability and stable yield.
