Abstract

Using yield data of twenty six mutant wheat genotypes, which had been cultivated in six environments of Valdivia, the genotype x enviromnent interaction was estimated and analysis of temporal stability of yield using AMMI model was accomplished.
The magnitude of the genotype x enviromnent interaction was determined using a combined variance analysis. Yield stability was estimated through the Additive Main effects and Multiplicative Interaction model (AMMI) of Zobel et al (1988).
Results indícate genotype x enviromnent interaction; effect of genotype and effect of enviromnent showed significance. The PCA-1 points of the AMMI model, showed six genotypes with smaller interaction effects and therefore higher stability behavior, these were M08, Mil, M12, M15, M16 and M19.
