The aim ofthe experiments was to evaluate new and promising varieties and hybrids ofspring grain crops of domestic and foreign selection and to identify the most adapted ones to the conditions of the Kaluga region. In the experiments, traditional methods of field tests were used. As a result of the research, it has been revealed that on average for three years, the biological yield of wheat grain was up to 2.8-4.5 t/ha on gray forest soils.

The paper presents an analysis of spring soft wheat varieties of different periods of variety change according to ecological plasticity and stability when cultivated in different climatic conditions (2014-2019). To increase the yield of spring soft wheat varieties, much attention is paid to the devlopment of high-intensity forms that respond positively to additional investments in agricultural technology. These varieties must also demonstrate high yield stability as well as plasticity in relation to environmental factors - i.e.

Cereal thrips are ubiquitous, widespread and strong pests of grain crops. Imago and larvae of thrips can damage leaves, ears, flowers and grains by injecting and sucking plant juices. Thrips reduce not only the weight but also the sowing qualities of grain, posing a threat to breeding and seed crops. Cereal thrips are a systematically and biologically diverse group of species that are difficult to diagnose and study. Morphological diagnosis of thrips is carried out according to the adult phase; diagnosis of larvae of closely related species requires the use of molecular genetic methods.
