几个甘蔗品种比较试验

Comparative Test on Several Saccharum Varieties

[目的]比较分析几个甘蔗(Saccharum)品种的主要农艺性状、主要经济性状、病虫害及抗倒情况。[方法]2010～2011年在广西北海市对云蔗03-194等10个甘蔗品种进行1年新植、1年宿根比较试验,以新台糖22号为对照。[结果]柳城05-129、粤糖00-318表现比较突出,柳城05-129新植、宿根蔗糖分比对照品种分别高0.07、1.30个百分点,新植、宿根产量分别比对照高0.05、22.6 t/hm2;粤糖00-318新植产量比对照高16.39 t/hm2,宿根蔗糖分比对照高0.93个百分点。桂糖02-351的宿根性表现较好,病虫害发生率小,宿根的产量、糖分分别比对照高0.93 t/hm2、0.93个百分点。[结论]该研究可为筛选出适合广西地区推广的优良甘蔗品种提供参考。

[Objective] The aim was to compare and analyze several Saccharum varieties′ main agronomic traits,main economic traits,plant diseases and insect pests,and lodging-resistance situation.[Method] Comparison test between one-year old plant and one-year old perennial root of ten Saccharum varieties was carried out at Beihai City,Guangxi in 2010-2011,taking Xintaitang No.22 as control.[Result] Liucheng 05-129 and Yuetang 00-318 showed more prominent.The sucrose content of Liucheng 05-129＇s one-year old plant and one-year old perennial root was higher by 0.07 and 1.30 percentage than those of control,resp.,and their yield was higher by 0.05,22.6 t/hm2 than those of control,resp.;The sucrose content of Liucheng 05-129＇s one-year old perennial root was higher by 0.93 percentage than that of control,and the yield of its one-year old plant was higher by 16.39 t/hm2 than that of control.Guitang 02-531＇s ratoon character showed better,plant diseases and insect pests＇ incidence rate was a little,and its perennial root′s yield and sucrose content was higher by 0.93 t/hm2,0.93 percentage than those of control.[Conclusion] The study provides a reference for selecting good Saccharum varieties planting in Guangxi region suitably.
