Based on the studies conducted using SNP-typing, a group of varieties was identified as the Orel biotype. The article shows the genetic and phenotypic features of plants of this biotype. It was emphasized that according to the results of the NDVI index assessment, the varieties of the Oryol biotype are distinguished by the relatively rapid nature of the development of the first half of the vegetation with the accumulation of a high level of biomass (0.89), which, at moderate rates of the reproductive phase, allows them to more effectively realize their potential in relation to varieties of other biotypes. Among the features of the structure of plant productivity, their high individuality in the productivity of the ear is highlighted, which is associated with the number of spikelets in the ear, percentage of kernel and grain weight (more than 2.0 grams). The noted parameters allowed the varieties of the Oryol biotype to show a high level of yield in the breeding nurseries of 2022, and in the environmental test with the varieties of other breeding centers to form a productivity of more than 150 centners/ha (Yermolovka, Shchelkovo 1 and Shchelkovo 2). According to the results of the study, the breeding sample of Shchelkovo 1 called Socrates was transferred to the State Variety Testing of the Russian Federation.
