Rye (Secale cereale L.) is an important crop in Europe, where it occupies about 90% of the world's area cultivated with this cereal (FAOSTAT, 2018), mainly in the countries of Central and Eastern Europe. The main research highlights the mechanisms of adaptation of rye culture to climate change, aimed at identifying genotypes that have a good behavior in culture under conditions of abiotic (thermohydric) and biotic stress (pathogens and pests) in order of restoring the production capacity and protection of agroecosystems in the area of sandy soils by promoting in culture some genotypes tolerant to thermohydric stress. In the two experimented years of 2020 and 2021 the obtained results prove the new genotypes promoted on the market had a higher capacity of production than the Control (Suceveana variety), with an average yield of over 4555 kg/ha registered at Serafino genotype in the conditions of a sandy soil with a low natural fertility, poorly supplied with total nitrogen (0.05- 0.07%). In average, during the tested years, the attack frequencies of pests manifested in the comparative rye culture, as well as the attack intensities did not show significant differences from one variety to another, significant differences compared to the control variety (Suceveana) being observed only in the case of Serafino variety.
