A new soft winter wheat variety of the universal type ovaciya with an economic and valuable traits complex

The purpose of research is the synthesis of new adaptive, competitive, universal wheat genotypes with a complex of the most important economic and biological traits for cultivation using intensive and medium-intensive technologies in the agroecological conditions of the North Caucasus, the Lower Volga and the Central Black Earth Regions of cultivation. A new genotype of wheat of the universal type Ovaciya was created in the North Caucasian Federal Scientific Agrarian Center (the Stavropol Region) based on the methods of classical and marker breeding using individual, continuous targeted selection according to the characteristics of the developed model of competitive, adaptive wheat genotypes. When it was created, the following were involved in crosses: the Don 95 variety as a mother plant and the Vassa variety as a paternal plant. The morphology and economic and biological characteristics of the variety are presented. It has a high grain yield. On average, over the years of study (2019-2021), its yield was 9.14 t/ha, which is 1.51 t/ha higher than the Grom standard. Ovaciya has a high number of grains in the ear, the weight of the grain of the ear and the weight of 1000 grains. These main elements of the structure of grain yield in the new genotype were significantly higher than the standard. According to a set of indicators of the quality of grain, flour and bread, it meets the standard of the Russian Federation for strong wheat. This variety is characterized by high winter hardiness and frost resistance, and in this respect it significantly and considerably exceeded the frost-resistant Grom wheat variety. The genotype of the variety has a high field resistance to a complex of diseases (brown, yellow and stem rust, powdery mildew, loose smut, pyrenophorosis, septoria, fusarium, barley yellow dwarf virus). The maximum damage by these pathogens during the years of the study was up to 5 %. A new variety is recommended for study on variety plots in the sixth, eighth and fifth regions of the Russian Federation. Possessing resistance to lodging, field resistance and tolerance to major diseases, energy intensity and responsiveness to nutrients, agrotechnological and soil-climatic conditions, the new variety Ovaciya should be attributed to varieties of resource-energy-saving technologies.
