摘　　要：【目的】筛选参加广西玉米区域试验优良新品种组合,为广西玉米生产提供支撑。【方法】在广西5个玉米综合试验站点设置玉米新组合筛选鉴定联合试验,对2019年秋季玉米新组合产量结果进行试验分析。【结果】从多点试验结果看,“桂A354”“HC543”表现特别稳定高产,在5个试验点中均比对照产量增产5%以上;“桂A331”“桂A324”“桂A345”“桂A327”表现稳产高产,在4个试验点中均比对照产量增产5%以上;90个参试品种中5个试验站平均产量在4.2~8.6t/hm2,共有35个供试新组合比对照品种增产,增产幅度在0.6%~24.2%,按平均产量增减百分率高低排位,前10名供试品种依次是:“桂A354”“HC543”“桂A306”“桂A303”“19下HP14”“桂A345”“19下HP04”“YZ18A-76”“HC178”“19下HP10”。【结论】从平均增产前10名和4个以上玉米综合试验站点表现增产5%以上共16个品种中,合并3个重复品种,共筛选出13个品种,即:“桂A354”“HC543”“桂A331”“桂A324”“桂A345”“桂A327”“桂A306”“桂A303”“19下HP14”“19下HP04”“YZ18A-76”“HC178”“19下HP10”,建议推荐参加2020年广西玉米新品种联合评比试验。【Objective】To select and participate in the regional trial of good new varieties of maize in Guangxi to provide support for the production of maize in Guangxi.【Method】The new maize combination identification test was carried out in 5 maize test sites in Guangxi to screen out new maize combinations with high yield and high quality.【Result】The results showed that there were 2 combinations for more than 5%increasing production in the five test sites:"GUI A354"and"HC543",indicating that the 2 combina⁃tions have particular high and stable yield.There were 4 combinations of more than 5%increasing produc⁃tion in the five test sites:"Gui A331","GUI A324","GUI A345","GUI A327",which showed that the 4 combinations have good high and stable yield.The average yield of 5 maize test sites in the 90 varieties was 4.2~8.6 tons/ha,35 new combinations increased yield by 0.6%~24.2%compared with the control,and the top 10 varieties increased yield were:"GUIA354","HC543","GUI A306","GUI A303","19-low⁃er-HP14","GUI A345","19-lower-HP04","YZ18A-76","HC178","19-lower-HP10".【Conclusion】The top 10 maize yield and more than 4 comprehensive test sites of maize yield increase showed the data of yield increase,combined with three repeated varieties,13 varieties were selected:"GUIA354","HC543","GUI A331","GUI A324","GUI A345","GUI A327","GUI A306","GUI A303","19-lower-HP14","19-lower-HP04","YZ18A-76","HC178","19-lower-HP10",and recommended to participate in the joint evaluation test of new maize varieties in Guangxi in 2020.
