Abstract

Yield performance and genotype x environment (GxE) interaction of sugarcane genotypes was evaluated across different environments in the Philippines in a multi- environment trial (MET). Significant effects of genotype, environment, and GxE were detected P < 0.001) with environmental effects accounting for most of the explained variability (80%). Weighted AMMI analysis (W-AMMI) helped address heterogeneity across test environments and showed that the first interaction principal component (IPCA) explained most of the variation due to GxE. Floridablanca (FB) contributed the least GxE information and was found to be redundant with Los Baños (UPLB) and EB Magalona (EM), whereas La Granja (LG) exhibited a unique secondary interaction pattern. AMMI and GGE biplot analyses identified J39-530M (G2) as a stable hybrid with the highest mean sugar yield across environments relative to the national checks. The which-won-where view of the GGE biplot identified genotypes with specific adaptations, with 2019-6-2 (G35) performing best in Los Baños, and EB Magalona; 2017-011 (G42) in La Granja and Floridablanca; and 2018-H17 (G36) in Digos and Matalam. These results provide basis for optimizing sugarcane METs and selecting promising hybrids.
