Perennial grasses play the most important role in solving the problem of production of energy-saturated high-protein bulky feed and biologization of agriculture. Perennial grasses are the most affordable and stable source of cheap plant food and a means of preserving soil fertility with intensive farming, which has an anthropogenic negative impact on agroecosystems. Perennial grasses play a special role as a biological means of countering the degradation of biological, water-physical and agrochemical properties of soils, their dehumidification and erosion processes. In arid climates, the most effective species of perennial bluegrass is the comb-shaped Wheatgrass (Agropyron peintforme Roem et Schult.). Compared to two other species used in agricultural practice – Siberian (sand) granary (Agropyron fragile (Roth) P. Candargy) and desert (narrow-leaved) (Agropyron desertorum (Ksch. ex Link.) Schult), the comb-shaped wheat grass is characterized by a wider range of growth, high productivity and environmental plasticity. In the State register of breeding achievements approved for use in Russia as of 2020, only 10 varieties of comb-shaped wheat grass are registered, which limits the effective use of this crop and makes it necessary to intensify breeding work in order to create new varieties with improved economic and useful characteristics. At the Voronezh experimental station, active breeding work is being carried out on perennial grasses to develop new varieties of comb-shaped wheat grass. Currently set up and ready to transfer to a new variety of Pridonskoy, characterized by drought tolerance, high forage and seed productivity and longevity. Thus, when the washed-out slopes were grazed, the abundant participation of the granary in the grass mixture was noted in the third year. From the fifth year, the granary dominated the herbage, and in the 10th-12th year of use, the cenoses were represented only by the granary.

A brief review of the efficiency of cultivation of perennial ryegrass in the areas of steppe and forest-steppe zones is given. The necessity of breeding varieties of perennial ryegrass adapted for use in the conditions of the Central Black Earth region is shown. A brief characteristic of the variety of ryegrass perennial Voronezhskiy (selection of Voronezh Experimental Station for perennial grasses) is presented. The variety is included in the state register in all regions of the Russian Federation. It is characterized by high winter hardiness, drought resistance, longevity. Recommended for sowing as part of grass mixtures when creating hayfields and pastures on various soil types (except sandy), including when reclaiming de-graded land, as well as creating cultivated irrigated pastures in the steppe zone and as part of grass mix-tures when creating meadow-type lawns. The main technological parameters of cultivating the variety for seeds are included, including optimal sowing time and seeding rates, a rational system of fertilizers, the use of herbicides, harvesting, autumn cutting of grass stands, sorting features that allow maintaining tetraploid level of sorting population during reproduction.

Among the perennial bluegrass grasses, the awnless brome is the most popular and widespread crop in the herbage of Russia. All varieties of awnless brome egistered in the State Register are of the hay-pasture type of use. A new source material of a awnless brome lawn-pasture eco-type seedling with high decorative properties has been created.
