Oleg Georgievich Davydenko (и. 04.03.1951, Kostroma, Russia), a scientist in the field of genetics and plant breeding. Corresponding Member of the National Academy of Sciences of Belarus (2000), Doctor of Biological Sciences (1990).
He investigated the interaction of nuclear and cytoplasmic genetic systems, the role of the genomes of cytoplasmic organelles in evolutionary and selection processes. Proved the possibility of induction of cytoplasmic mutations in agricultural plants (maize, wheat, soybean, sunflower); the presence of intraspecific cytoplasmic variability that controls the productivity and fitness of plants; revealed the effects of cytoplasmic genes on the change in cleavage and the frequency of recombinations of nuclear genes; formulated theoretical statements on the mechanisms of interaction of nuclear and cytoplasmic genetic systems of a plant cell and their use in the selection of agricultural plants; developed methods and principles of adaptive breeding of soybeans for the conditions of northern latitudes. He conducted large-scale studies of the genetic polymorphism of the indigenous population of Belarus, which provided additional information on the origin and ancient history of the Belarusian people.
Author of about 250 scientific papers, including 5 monographs, a textbook, 9 plant varieties.
Prize of the National Academy of Sciences of Belarus in 2003, Prize of the Siberian Branch of the Russian Academy of Sciences and the National Academy of Sciences of Belarus named after academician V.A. Koptyug in 2007.
