摘　　要：为筛选适应干旱气候的优良甘蔗新品种,在来宾蔗区选择13个甘蔗新品种开展自然干旱条件下甘蔗品种筛选及评价试验。结果表明,与对照桂糖42号相比,桂糖11-2011、桂糖60号表现优异,应重点关注并加大推广应用,其中桂糖60号应注意螟虫防治;桂糖46号耐旱性能好,蔗糖分表现中等;桂糖44号、桂糖49号、桂糖55号、桂糖57号也有较好表现,可继续关注并加大推广应用;桂糖59号生长表现好,但蔗糖分偏低,还需继续观察其糖分表现,且应注意螟虫防治;桂糖58号生长表现略优于对照,早期糖分偏低,可作为中晚熟品种推广。本研究结果可为来宾蔗区及同类型蔗区引进和推广优良新品种提供参考和数据支持。In order to select new sugarcane varieties adapting to drought climate,13 new sugarcane varieties were selected in Laibin sugarcane area to carry out screening and evaluation experiments of sugarcane varieties under natural drought conditions.The results showed that compared with the control(Guitang42),Guitang11-2011 and Guitang60 performed well,and took more attention and recommended,and it was necessary to control borers for Guitang60;Guitang46 had good drought tolerance and medium sugar content;Guitang44,Guitang49,Guitang55 and Guitang57 also had a good performance,and should also be paid more attention to and recommended;Guitang59 had a good growth performance,but its sugar content was low,so it was necessary to continue to observe its sugar performance and pay attention to the control of borers;the growth performance of Guitang58 was slightly better than that of the control,and the sugar content in the early stage was low,so it could be popularized as a middle and late maturing variety.The results of this study could provide a reference and data support for the introduction and popularization of fine new varieties in Laibin sugarcane area and other similar sugarcane areas.
