The objects of research were the groves of the Central Chernozem and plus trees selected in them. Oakwood in the re-gion has long been intensively exploited, their area reduced by 2-3 times, and the gene pool is severely malnourished. Restor-ing oak occurs very difficult with large omissions and economic costs. The main reason is the lack or total absence of acorns high quality selection. Research is devoted to the knowledge of the regularity and fruiting oak plus trees.
