Abstract. The research was carried out to study the genotype-environmental interactions of spring durum wheat varieties created during different breeding periods at the Samara Agricultural Research Institute, to determine evolutionary trends in the profile of response in yield and grain yield stability. The work was carried out in the Samara region in 2015–2021. 12 varieties of 4-6 stages of selection were studied. The duration of one stage was equal to 19 years from the start of selection in 1912. The years of research were divided into 3 groups: favourable – 2017 and 2021 (HTC 1.26 and 0.66), average – 2015 and 2020 (HTC 0.68 and 0.38), unfavourable – 2016, 2018 and 2019 (HTC 0.46; 0.45 and 0.55). To determine genotype-genotype-environment interactions, three GGE biplot models were used with a help of the Genstat 12 programme – “which genotype won where”, “productivity and stability by average environmental values”, and “correspondence to the ideal genotype”. The most adapted to the “mega-environment” in the biplot “which genotype won where” were varieties of the 6th stage – Bezenchukskaja krepost', Bezenchukskaja 210, Bezenchukskaja zolotistaja, Pamjati Chehovicha. The varieties Bezenchukskaja niva and Marina (6th stage) were marked on the graph in the border area with a "mega-environment", that brings them closer to varieties of wide adaptability. The varieties of stages 4-5 Bezenchukskaja 139, Bezenchukskaja 182 did not show competitiveness in the studied environments. Bezenchukskaja zolotistaja, Bezenchukskaja niva, Bezenchukskaja krepost', Bezenchukskaja 210, Marina and Pamjati Chehovicha (stage 6) in the biplot "productivity and stability by average environmental values" were in the area of high yield and stability. Bezenchukskaja 139 (stage 4), Bezenchukskaja 182, Bezenchukskaja stepnaja (stage 5) had low yield and stability ranks. Bezenchukskaja krepost', Bezenchukskaja zolotistaja, Bezenchukskaja 210, Bezenchukskaja niva (6th stage), in terms of yield and stability, were close to the "ideal" genotype.
