Remained Faithful to Science (P.P. Zvorykin)

The article sets the task of reconstructing the biographical outline of the repressed geneticist and breeder agronomist P.P. Zvorykin. The scientist created experimental breeding stations in the center of the European part of the USSR, Central Asia, Western Siberia, and in the north. The analysis of scientific and organizational activity of a scientist helps to reveal his contribution to the assimilation and development of new theoretical and practical results of genetics and breeding. In the Komi ASSR, from the standpoint of genetics, he studied the possibilities of breeding and introduction of agricultural crops of grain, garden, meadow grasses, and prepared for the defense of his dissertation. The documents of the agricultural experimental station in Ukhta collected by Zvorykin are of scientific value and are stored in the Scientific Archive of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences. The source base of the research includes documents from several archives.
