GGE biplot analysis allowed selection of the sugarcane cultivar PR75-2002 as second for
average cane yield and with broad adaptation (stable).
Two groups of environments (mega-environments) were defined; the first made up of seven
environments and the second one of two environments. The winning cultivars with the highest cane
yield were CG00-120 and CG00-092 for each of the groups (specific adaptation) respectively.
The G main effect and GE interaction can be exploited by selection of highest cane yield
cultivars for each mega-environment.
