摘要: The objective of this study was to propose a methodology using factor analysis associated with genotypic and genotype × environment interaction effects (FGGE) accomplish, simultaneously, analyses environmental stratification the adaptability maize cultivars indicated for planting in Parana State. based on accomplished graphically by scoring relation factors separation quadrants. were beginning magnitude final loadings obtained after rotations through varimax method. FGGE method is efficient processing analysis. More than 70 % retained variation first eigenvalues represents expressive part sum (G × E) data set. wide adaptation high yield group tested environments P30F35, P30F53, P30K64, P30R50 AS 1570.
