Ongoing global warming makes the selection and deployment of tolerant olive cultivars a strategic priority for sustainable agriculture and for mitigating the negative impacts of heat stress. Warm summers markedly reduce the performance and quality of olive plants. In this context, the present study evaluated 41 olive cultivars, including 17 genotypes from Kermanshah (Ds1, Ds2, Ds3, Ds4, Ds5, Ds7, Ds8, Ds10, Ds11, Ds12, Ds13, Ds14, Ds16, Bn1, Bn2, Bn5, D1), 13 genotypes from Ilam (Ske7, Ske8, Pg1, Pg3, Bsch1, Bsch2, Bsch3, Sbm5, Kf8, Dz1, Dz4, Ns3, Ns4), 3 genotypes from Tarom (T2, T3, T7), and 5 genotypes from Gorgan (B1, B3, G4, M6, E2), along with 3 control cultivars (Zard, Amygdalolia and Amphysis), by examining their pomological traits, olive oil, fatty acids profile and molecular analysis under rising summer temperature at the Dallaho Olive Research Station (Sarpole-Zahab in Kermanshah) province in 2023.
