摘　　要：闽糖 86-2121 是福建省农科院甘蔗研究所 1985 年以 Q61 为母本 CP49-50 为父本的杂交组合选育出的一个优良甘蔗品种 该品种具有高产高糖 中晚熟 宿根性强 抗逆性强 适应性广的优良特性在福建多年多点试验结果表明 闽糖 86-2121 蔗茎产量 118.516 t/hm2 11 2 月份平均蔗糖分 绝对值14.65 含糖量 17.363 t/hm2 比福建目前主栽品种闽糖 70-611 增产 35.60 蔗糖分提高 0.26 个百分点 增糖 52.1 该品种在全国甘蔗品种第 3 轮区试和生产试验中 平均蔗茎产量 123.331 t/hm2 112 月平均蔗糖分 13.80绝对值 含糖量 16.984 t/hm2 比全国对照种 ROC10 分别增加 22.97 蔗糖分减少 0.24 个百分点 增糖 20.Mintang86-2121, selected from the cross combination of Q61 and CP49-50, is a new sugarcane variety with middle to late maturity, high yield and sucrose content, stronge ratooning ability, high adverse resistance and wide adaptability. The results from different sites for several years in Fujian showed that its mean cane yield was 118.516t/hm2, sucrose content of cane (absolute value) was 14.65% during the period of Nov. to Feb, sugar yield was 17.363 t/hm2 and was 32.10%, 0.26% and 34.49% higher than that of the currently leading variety Mintang 70-611 in Fujian Province, respectively. And the results from the third round Regional Trial of National Sugarcane Varieties and production experiment showed that its mean cane yield was 123.331 t/hm2, sugar yield was 16.984 t/hm2, sucrose content was 13.80%(absolute value) during Nov. to Feb and was 22.97%, 22.3% higher and 0.24% lower than the CKs of national variety ROC10.
