The population of Festuca Arundinaceae Sherb. The cretaceous south of the middle Russian uplands as a starting material for the selection of grass bearing varieties

Abstract

The genetic resources of wild populations of Medicago falcate L. of the Cretaceous South of the Srednerussky Upland in ecotopic conditions of chalky slopes and floodplain meadows in the basins of small rivers Tikhaya Sosna and Manjokha were studied to find the source material for breeding work to create varieties for different cultivation conditions. Evaluation of phytocenotic features, density of cenopopulations, forage and seed species was carried out. The species M. falcata forms, both on meadows in floodplains and on chalk slopes, full-membered normal cenopopulations, which have a continual (continuous) distribution of individuals by age groups, stable in time and in space
