Breeding of agricultural plants, rice in particular, is a fundamental factor in providing the country's population with a sufficient amount of high-quality products. Hence, the level of breeding achievements and agricultural technologies determines the food security of the country and the competitiveness of the industry in the international market. The scientifically based introduction of new, better varieties into production contributes to the growth of not only the yield, but also to an increase in the yield of products and an improvement in its quality. Therefore, the role of the variety as a means of agricultural production in modern agriculture is undoubtedly important. The paper presents the results of a breeding program on developing large-grain rice variety Vector, capable of forming a high grain yield - 9.0-10.0 t/ha with high technological indicators - 89.5% of head rice content with 69.8% of the total milling yield, which in conversion is approximately 62.4% of the head rice in the grain mass. At the same time, new rice variety Vector, according to grain size, belongs to the category of large-grain varieties with a mass of 1000 grains - 34.5 g with an average filminess of 17.7% and vitreousity - 83.5%. Also, during the study period (2020-2022) of the new rice variety Vector, resistance to the Pyricularia pathogen was found in natural conditions. With artificial infection, the disease development index averaged 37.0%, which corresponds to medium resistance. Based on the results of the work, the Vector variety was submitted for state testing (SVT). A comprehensive and positive assessment of the SVT will allow it to be entered into the State Register and recommend the variety for cultivation in the conditions of Krasnodar region and the Republic of Adygea.
