甘蔗新品种闽糖92-649的选育研究

闽糖92－649是福建省农科院甘蔗研究所以新台糖1号为母本、Coloo1(闽选703）为父本为杂交组合选育出的甘蔗新品种。该品种具有高产高糖、中早熟、宿根性好、抗逆性强、适应性广的优良特性。经福建省多年多点试验，结果表明，闽糖92－649蔗茎产量为114.178t/hm^2,11-2月份平均蔗糖分为15.36%，含糖量为17.44t/hm^2，分别比福建目前主栽品种闽糖70－611增加35.6%、1．71％（绝对值）和52．1％。该品种在全国甘蔗品种第二轮区试和生产试验中，平均蔗茎产量93.18t/hm^2,11-2月份平均蔗糖分14．48％，含糖量12.98t/hm^2，比对照种新台糖10号分别增加24.5%、0.04%（绝对值）和22.3%。

Selection and Breeding of New Sugarcane Variety Mintang 92-649

Mintang 92-649, selected from the cross combination of ROC1 and Co1001 (Minxuan 703), was a new sugarcane variety with early to middle maturity, high yield, high sucrose content, high adverse resistance and wide adaptability. The results from different sites for several years in Fujian showed that its mean cane yield was 114.178 t/hm2, sucrose content of cane (absolute value) was 15.36% during the period of Nov. to Feb, sugar yield was 17.44 t/hm2 and was 35.6%, 1.17% and 52.1% higher than that of the currently leading variety Mintang 70-611 in Fujian Province, respectively. And the results from the second round Regional Trial of National Sugarcane Varieties and production experiment, its mean cane yield was 93.18 t/hm2, sucrose content of cane (absolute value) was 14.48% during the period of Nov. to Feb, sugar yield was 12.98 t/hm2 and was 24.5%, 0.04% and 22.3% higher than that of the CK of national variety, ROC 10.
