The role of the genetic and epigenetic component in the formation of the natural genetic load and fitness of M5-mutant posterities of perennial сross-pollinated grass Festuca pratensis Huds. is shown. M5-mutant generations were created at different levels (high, moderate and low) of soil fertility nutrition available to maternal plants. The size of the seedling pool with a suppressed chlorophyll deficiency, survival and fertility of plants, influence of stabilizing natural selection as applied to the above components of fitness were estimated.
