甘蔗新品种闽糖92-505的选育研究

Selection and breeding of new sugarcane cultivar Mintang 92-505

闽糖92-505是福建省农科院甘蔗研究所以选15为母本、CP73-1547为父本的杂交组合中选育出的一个优良甘蔗新品种,该品种具有高产高糖、早熟、宿根性强、抗逆性好、适应性广的优良特性。在福建多年多点试验结果表明,闽糖92-505每公顷蔗茎产量118.424 t,11月至翌年2月份平均蔗糖分(绝对值)15.06％,每公顷含糖量17.887 t,比福建目前主栽品种闽糖70-611增产24.30％、蔗糖分提高0.87个百分点、增糖32.20％。

Mintang92 -505 selected from the cross combination of Xuan 15 and CP73 -1547, was a new sugarcane cultivar with early mature, high yield and sucrose content, stronger ratooning ability, high adverse resistance and wide adaptability. The results from different sites in Fujian for several years showed that its mean cane yield was 118. 424t · hm^-2, sucrose content of cane （absolute value） was 15.05% during the period from Nov. to Feb. next year, sugar yield was 17. 887 t · hm^-2 and was 24.30%, 0. 87 percent points and 32.20% higher than those of the currently leading cultivar Mintang 70-611 in Fujian Province respectively.
