摘　　要：The experiments of sugarcane combination evaluation were conducted on 119 combinations during 2017-2018 crossing season in Nanning,Chongzuo and Laibin of Guangxi.The conjoint analysis of variance and estimation of genetic parameters were performed based on brix weight.Furthermore,combination stability was analyzed by regression analysis model and AMMI model.The results showed that differences in brix weight among combinations,environments and interaction between environments and combinations were all extremely significant(P<0.01),and the broad-sense heritability of brix weight belonged to medium level or slightly lower at the three sites.In both Chongzuo and Laibin,the variation coefficients of brix weight were large,but that in Nanning was small.Combinations 643,404,575,972,636,144,YC95,1470,755,409,701,832,YC37 and 579 performed high yield,high genetic stability and stronger adaptability.The results of comprehensive analysis in both brix weight and selection rate of combination showed that 449,YC127,796,YC44,533,570,YC123,391,546,403,YC90 and 252 performed high brix weight and high selection rate of combination in Nanning;combinations 643,212,YC61,432,903,YC95,YC44,368,YC83,YC127,YC112,701,411,YC90 and YC123 demonstrated high brix weight and high selection rate of combination in Chongzuo;and combinations 643,404,449,144,403 and YC48 had high brix weight and high selection rate of combination in Laibin.
