Contacts between N.I. Vavilov (VIR) and Yu.A. Filipchenko (Dept. of Genetics, Leningrad State University) reflect close interaction of science and education in fundamental and applied genetics at the first halve of XX century. This interaction put the basis for the future Institute of Genetics of the USSR Academy of Sciences, the first director of which became N.I. Vavilov at 1933. 1932 by Vaviliv’s initiative there had been organized Dept. of Plant Genetics in the University under leadership of Karpechenko. Müller and Bridges had been teaching in the University being invited by Vavilov in Institute of Genetics. The revival of genetics in the University at 50-s of XX century, after lysenkoism period, proceeded under the influence of Vavilov even perished 1943 in prison. The role of Lobashev and Feodorov in those events is evident.
