Abstract
Relevance. Potato hybrids obtained when creating varieties adapted to the weather conditions of the Komi Republic must have maximum resistance to constantly changing environmental conditions while maintaining the yield indicator at a high level. In addition, breeders impose requirements for their high field resistance to the main diseases common in the region: late blight, alternaria, rhizoctonia, scab and viruses (X, Y). In 2020, in the course of a continuously operating selection process, produced on the basis of the Institute of Agrobiotechnology FRC Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences (Syktyvkar) together with the FRC potato named after A.G. Lorkh (Korenevo), samples were taken from the nursery of the main test of hybrids.
Methods. The studies were carried out on five hybrids sent from the FRC of Potato named after A.G. Lorkh obtained by hybridization of the original parental forms, growing hybrid seedlings and single-root hybrids, followed by selection in nurseries of single-root hybrids, second-year hybrids, preliminary and main tests already directly at the Institute of Agrobiotechnology FRC of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences. Observations, counts and culling in each nursery were carried out in accordance with the methodological recommendations on the technology of the potato breeding process. According to the research results, the hybrids were assessed in terms of yield, yield range (the difference between the maximum and minimum values for the study period), realization of yield potential (the ratio of the average yield to the maximum over the years of research) and coefficient of variation, as well as disease resistance.
Results. As a result of a comprehensive assessment of potato samples in the nursery of the main test, three promising hybrids were identified — 1992–14, 2000–60 and 2139– 5 with an average yield at the level of standard varieties and higher (23.6–31.2t/ha), having a high stability and disease resistance.
