Molecular genetic analysis of promising potato hybrids of the Komi Republic (Russia)

Abstract

Potato varieties with a complex of economically valuable traits, such as high yield, quality, disease resistance, are the key to successful competitive production in the Komi Republic (Russia). Agribusiness is increasingly demanding high field resistance of varieties to the main diseases and pests common in the region - viruses (X, Y), nematodes, etc. The Institute of agrobiotechnology of the Federal Research Center of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences (Russia, Syktyvkar) together with the FRC of Potato named after A. G. Lorkh (Russia, Lyubertsy) continuously conducts the process of obtaining new varieties of potatoes that are adaptive to the soil and climatic conditions of the North of Russia, having high field resistance to phytopathogens. A promising potato hybrid 2000-60, characterized by a complex of resistance genes to the golden potato nematode H1 (TG-689, 57R, N195) and potato cancer NL25 (Sen1), was isolated in the course of a comprehensive assessment of potatoes using the methods of molecular genetic analysis of gene markers. Based on the molecular genetic analysis of potato genes, hybrids 2339-8 and 1992-14 are recommended for crossing and obtaining new breeding lines in order to develop new potato varieties resistant to various types of nematodes.
