%X Stability and adaptability of 14 early maturing sugarcane clones were evaluated at 11 locations in the State ofParan¨¢, in the plant cane and ratoon cycles, by the AMMI method. By AMMI2, 59.44% cumulative variance was explained inplant cane and 54.22% in ratoon cane by the first two principal components of tons of pol per hectare (TPH). For genotypeRB966928 the TPH was medium to high, phenotypic stability high and adaptability general, recommending this early maturingclone with wide adaptability for northern Paran¨¢. The genotype-environment interaction was lowest in Paranava¨ª andMandagua ¨² (most stable locations), where the ranking of genotypes was more reliable than the means of the environmentstested.
