【摘要】 赣南99-591(亲系:粤糖83-257×CP57-614)是江西省甘蔗研究所选育的一个早熟高产高糖优良甘蔗新品种,具有宿根性能好、抗逆性能强、适应性广的优良特性。多年多点的试验结果表明,赣南99-591蔗茎产量96.81t/hm2,11月底平均蔗糖分14.67%,含糖量14.20t/hm2,比目前主栽品种赣蔗14号增产15.54%,蔗糖分提高0.55个百分点,产糖量增糖20.1%。更多还原

【Abstract】 Gannan 99-591, derived from the cross YT83-257×CP57-614, was selected by Jiangxi Sugarcane Research Institute. Results from varietal trials and provincial regional trial indicated that Gannan 99-591 was an early maturing, high yielding and high sugar variety with strong ratooning and good adaptability and resistance. The average cane yield, sugar yield per hectare and sucrose content in late November of Gannan 99-591 were 96.81 t/hm2, 14.20 t/hm2 and 14.67%, respectively, increased by 15.54% and 20.1% over, and 0.55% higher than those of GZ14, the local predominant cultivar in Jiangxi province respectively.更多还原
