Under pronounced climate changes, identifying wheat genotypes with high yield potential and stable performance across different environments has become increasingly important. This study evaluated the stability and adaptability of 15 wheat genotypes using multi-environment trials conducted across three locations in Serbia over two growing seasons. Genotype plus genotype × environment interaction (GGE) biplot analysis was applied to assess genotype performance for the number of grains per spike and to identify the most suitable environments for genotype evaluation. The results revealed that spelt wheat lines exhibited high values and moderate stability, while several bread wheat genotypes demonstrated both high stability and adaptability. Pančevo in the 2023/2024 season was identified as the most representative and discriminative environment, providing a reliable basis for genotype evaluation. These findings support the selection of stable and well-adapted wheat genotypes for future breeding programs.
