Abstract: The objective of this work is to evaluate the adaptability and phenotypic stability of the RB sugarcane genotype using the AMMI method. The experiments were performed in five production units in the state of Pernambuco, in cultivars of sugarcane soca and ressoca, using 14 RB sugarcane genotypes—11 RB clones of series 2004 and three cultivars as controls. Each combination of production unit × cutting was considered as environment, for a total of 13 environments. The experimental design was with random blocks, and four repetitions. We estimated the parameters tons of sugarcane per hectare (TCH) and tons of pol per hectare (TPH). The genotype G12 displayed general adaptability, phenotypic stability and high productivity for the two parameters. The genotypes G10, G13 and G14 had the highest yield, largest contribution of G×E, indicating specific adaptability. The environments A12 and A13, in Primavera, are recommended for preliminary selection trials.
