Adaptability Evaluation of Guire Series New Sugarcane Varieties(Lines)under Different Areas in Guangxi
To comprehensively comprehend the high-yield,stability,and adaptability of the Guire series sugarcane varieties(lines),it is imperative to identify new varieties(lines)suitable for regional planting in Guangxi.In order to establish a reference basis for the optimal distribution of sugarcane varieties and the future application and promotion of the Guire series.From 2016 to 2018,using Guitang42 and Guiliu05136 as controls,five experimental sites were set up in five locations(Liuzhou,Hengzhou,Nanning,Fangchenggang,and Beihai)to conduct adaptability evaluations in different areas.Eight sugarcane varieties(lines)were investigated for agronomic traits,pest and disease damage,sugarcane yield,and sugar yield,and the high-yield,stability,and adaptability of their main traits were analyzed.The results showed that except for the effects locations and between locations and varieties,the variation sources of sugarcane yield and sugar yield all reached significant or extremely significant levels.The cane yield of the Guire series sugarcane varieties(lines)is higher than that of the control Guitang42 and Guiliu05136,with significant differences between Guire2,Guire02-186,and Guire03-81 and the control;The sugar yield of Guire2 and Guire02-186 was higher than that of the control Guitang42 and Guiliu05136,with significant differences between Guire2 and the control.The best performing Guire2 increased yield and sugar content by 41.12%,32.76%,and 29.22%,21.42%,respectively,compared to the control Guitang42 and Guiliu05136,with a significant increase in yield and sugar content.Overall analysis shows that the sucrose content of the Guire series sugarcane varieties(lines)is lower than that of the control,and the maturity period is later,with medium to late maturing varieties.Guire2 exhibits excellent traits,high yield,high sugar content,strong resistance to smut,and wide adaptability.It can be widely promoted and planted in sugarcane growing areas,especially in hilly and sloping areas of Guangxi;The Guire02-186 has good yield and stability,and has a wide adaptability,which can be promoted and applied in some sugarcane areas;Guire1 has a certain adaptation area and can achieve higher cane and sucrose yields in coastal areas such as Changling and Binhai.It can be tested and promoted in this area,and the performance of its traits can be further observed;The performance of Guire03-81 and Guire03-23 is not very ideal,and it is not recommended to promote their application.In addition,the sugarcane varieties(lines)of Guire series had lower sucrose content than the control,and the ripening stage was late,so it was suggested that sugarcane areas could adopt early and middle.The varieties in the late maturing stage are arranged to plant the varieties of cinnamon fever,and the sugarcane can also be arranged to plant the sugarcane in the autumn,and the cultivation management measures such as reducing the application amount of nitrogen fertilizer as much as possible during the late growth of sugarcane,so as to improve the sucrose content of cinnamon fever series and promote the application in the sugarcane area.
