Comprehensive Evaluation of New Sugarcane Lines in Guangxi by DTOPSIS Method
[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]Three clones 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.
