Adaptability and stability analysis of common wheat production

Wheat is one of the most produced cereals in world and used manufacture various products that are consumed daily. As a result, there need to produce quality wheat regions world, meet demand reduce transportation costs. It versatile crop, all over with wide number cultivars adapted local conditions. This work had objectives comparing values genotype-environment interaction (GE) obtained using additive main effects multiplicative model (AMMI) analysis linear regression (LR) production stability common genotypes. Eleven genotypes were evaluated different environments (combinations location year) based on data field trials took place period from 2015 2019. The experimental design was randomized blocks, two repetitions. sum squares (SS) regressions only explained 21.6% SS GE interaction, while first component (PC1) components 46.3%. PC1 twice greater than combined (joint, genotypic environmental). Therefore, AMMI more efficient describing LR.
