摘要
粤糖1575是以稳产、宿根性极好的粤糖94-128为母本,以高糖高产的粤糖00-319为父本,有性杂交选育获得的甘蔗新品种。该品种种性表现为早中熟,高产高糖,宿根性好,有效茎多,抗黑穗病,抗寒性和耐旱性中等,全生长期生长快,后期尾力足,不早衰,适应性广,适宜机械化生产。2018~2021年粤糖1575参加全国甘蔗新品种第14轮联合区域试验结果显示:该品种1年新植2年宿根在16个试验点的平均蔗茎产量为96.3 t/hm^(2),比对照ROC22增产6.31%;11月至3月份的平均蔗糖分为14.99%,比对照ROC22增加0.16个百分点(绝对值);平均含糖量为14.85 t/hm^(2),比对照ROC22增加9.81%。16个试验点中,粤糖1575有11个试验点表现出增产,10个试验点表现出含糖量增加,其中以广西的河池、崇左、来宾、百色、龙州、北海、福建漳州、广东湛江、云南保山等地表现优良。由此可见,粤糖1575具有较高的推广潜力,适宜广西、广东、云南中等或中等以上地力的旱坡地、水旱田种植。该品种于2021年3月通过国家非主要农作物品种登记,登记编号为:GPD甘蔗(2021)440003。
Yuetang1575 was selected from the offspring of cross combination using Yuetang94-128 as female parent and Yuetang00-319 as male.The characteristic of Yuetang1575 was early and medium maturity,high cane yield and sugar content,resistance to smut,tolerance to cold and drought stress,fast growth in whole life,no premature senescence,and wide adaptability.The variety participated the 14th national regional test of sugarcane during 2018 to 2021.The average cane yield,average sugar content from November to March and sugar yield of Yuetang1575 were 96.3 t/hm^(2),14.99% and 14.85 t/hm^(2) during the process of one year new plant and two year ratoon,respectively,which were 6.31%,0.16%(absolute value)and 9.81% higher than the control(ROC22).Among 16 test points,Yuetang1575 showed increase of cane yield in 11 points,and the increase of sugar yield was found in 10 points.Yuetang1575 grew better in Hechi,Congzuo,Laibing,Baise,Longzhou,Beihai of Guangxi,Zhangzhou of Fujian,Zhanjiang of Guangdong,and Baoshan of Yunnan.Therefore,Yuetang1575 has high potential to spreading,and was suitable for planting in medium fertility irrigated land,dry land and paddy field in Guangdong,Guangxi and Yunnan.This variety passed the National Non-Major Crop Variety Registration in March 2021 with the registration number:GPD sugarcane(2021)440003.
