摘要
桂糖57号(品系名:桂糖08-1180)是广西壮族自治区农业科学院甘蔗研究所采用杂交育种方法选育出的甘蔗新品种。其母本为ROC26,父本为ROC22,于2008年播种实生苗,2015~2017年参加全国甘蔗品种第十一轮联合区域试验,2020年完成甘蔗品种登记。桂糖57号在全国区试的广西和广东2省(区)7个区域试验点的1年新植和2年宿根结果表明,桂糖57号平均蔗茎产量为103.8t/hm^(2),比对照ROC22增产2.14%。桂糖57号平均全期甘蔗蔗糖分为14.85%,比对照ROC22高0.47个百分点(绝对值)。桂糖57号平均含糖量为15.3t/hm^(2),比对照ROC22增产5.50%。桂糖57号种性表现为中大茎种、植株高度中等、有效茎数多、早熟高糖、高产、抗倒伏性强。桂糖57号在广西甘蔗主产区的崇左、来宾以及河池蔗区表现出较强的适应性。
Guitang 57(clone name:GT08-1180)was bred through hybridization breeding procedure by sugarcane research institute of Guangxi Academy of Agricultural Sciences,which female and male were ROC26 and ROC22 respectively.The true seeds of the combination for selecting GT57 was planted in hybrid nursery in 2008.GT57 participated in the eleventh combined regional trial of national sugarcane varieties from 2015 to 2017,and passed national sugarcane variety registration in 2020.The regional trial data of 1plant crop and 2 ratoon crops on 7 experiment sites of Guangxi and Guangdong province showed that the average cane yield of GT57 was 103.8 t/hm^(2),which was 2.14% higher than that of CK(ROC22).The average sucrose content of GT57 was 14.85%,which was 0.36%(absolute value)higher than that of CK.The sugar yield of GT57 was 15.3 t/hm^(2),which was 5.50% higher than that of CK.The varietal characteristics of GT57 exhibited mid-large stalk,medium plant height,rich stals,early maturity and high sucrose content,high yield and strong lodging-resistance ability.GT57 showed strong variety adaptability in Chongzuo,Laibin and Hechi sugarcane producing areas of Guangxi.
