The experiment across nine environments (three cuttings × three locations) was conducted during 2009-10 and
2010-11 crop seasons to study the effect of genotype × environment interaction (GEI) on a cane, CCS yield and sucrose (%) in sugarcane (Saccharum spp). Analysis of variance of 10 genotypes revealed that genotype, environment and GEI were highly significant. The additive main effects and multiplicative interaction (AMMI) model was used
to interpret the behaviour of genotype, environment and their interaction. In fact, the objective of this study was to identify stable and adaptable genotypes across the locations and to determine the magnitude of G×E interaction. AMMI analysis of variance showed that 52.93% of the total SS for cane yield, 60.48% for CCS yield ad 56.0% for sucrose (%) was attributed to the environmental effects, indicating that the locations were diverse. The PCA-1 and PCA-2 were also significant and both sums contributed cumulatively to 66.84% to the total of G×E interaction. The genotype CoP 05437 (4) exhibited high cane and CCS yield along with wider stability and adaptability to the different environments. However, BO 91 (8), CoSe 092423 (10), CoSe 05452 (5), Co 05019 (2) and CoBln 04174 (7) genotypes showed instability and specific adaptability to the environments, while CoP 09301 (9) genotype showed higher sucrose (%) and greater stability across the environments for this trait
