摘　　要：【目的】筛选出综合性状表现优良的品种。【方法】以广西8个甘蔗新品系为材料,‘新台糖22号’为对照品种,通过一新两宿的比较试验,对蔗茎产量、蔗糖分、产糖量等12项性状指标进行方差分析和DTOPSIS法评价。【结果】在8个材料中筛选出3个综合性状表现良好的品系,Ci的排序为‘柳糖10-17’(0.679)>‘桂糖12-1764’(0.650)>‘桂糖12-422’(0.634)。‘柳糖10-17’的蔗茎产量与产糖量均最高,蔗糖分较高,宿根性强,黑穗病发生率较低,可考虑延长宿根种植年限。‘桂糖12-1764’的出苗率高、宿根发株能力强,有效茎数多,蔗糖分和产糖量较高。‘桂糖12-422’的分蘖能力强,有效茎数最多,黑穗病和梢腐病发病率较低,蔗茎产量高和产糖量较高。【结论】‘柳糖10-17’、‘桂糖12-422’、‘桂糖12-1764’综合性状表现优良,适宜在广西柳州蔗区及气候条件相似蔗区推广种植。【Objective】In order to screen out the varieties with excellent comprehensive traits,【Method】8 new sugarcane lines from Guangxi were used as the material,with‘XTT22’as the control variety.A comparative experiment across plant crop and two ratoon crops was conducted,a total of 12 traits,such as sugarcane yield,sucrose content,and sugar yield were analyzed through both variance analysis and the DTOPSIS.【Result】Threeclones with good comprehensive performance were selected from the eight clones,and the Ci order was‘Liutang 10-17’(0.679)>‘Guitang 12-1764’(0.650)>‘Guitang 12-422’(0.634).The cane yield and sugar yield of‘Liutang 10-17’were both the highest,and the sucrose content was also higher.It had strong ratooning ability and a low incidence of smut disease,suggesting potential for prolonging harvests of ratoon crops.‘Guitang 12-1764’had a high emergence rate,robust ratooning and sprouting capacity,multiple millable stalks,and higher sucrose content and sugar production.‘Guitang 12-422’had strong tillering ability,the most millable stalks,low incidence rate of smut and Pokkah boeng,and high cane and sugar yields.【Conclusion】‘Liutang 10-17’,‘Guitang 12-422’,and‘Guitang 12-1764’showed excellent comprehensive traits and are suitable for promotion and cultivation in the sugarcane-growing areas of Liuzhou(Guangxi)and other regions with similar climatic conditions.
