Bread wheat (Triticum aestivum L.) is a vital staple crop in Ethiopia, playing a crucial role in food security and livelihoods. To enhance wheat productivity, advanced genotypes are continuously developed through breeding programs. In this study, we conducted field trials across multiple locations and seasons in Ethiopia to assess the grain yield performance of advanced bread wheat genotypes using the Additive Main Effect and Multiplicative Interaction (AMMI) analysis. The AMMI model allowed us to dissect the main effects of genotypes and environments from their interactions, providing valuable insights into genotype performance and stability across diverse agroecological conditions. Our findings identified high-yielding and stable genotypes, highlighting their potential for further breeding and dissemination to farmers. Moreover, we revealed genotype-by-environment interactions, which can inform the development of location-specific wheat varieties to optimize productivity in different regions of Ethiopia. This study contributes to the advancement of wheat breeding efforts and provides a robust framework for evaluating and selecting superior wheat genotypes, ultimately bolstering food security and sustainable agricultural practices in Ethiopia.
