The article highlights the work with genetic resources of perennial koelerias and legume grasses in the Precarpathian Department of Scientific Research of the Institute of Agriculture of Carpathian region of NAAS, Ukraine. The results of the systematization of the collection, which includes 1762 samples of domestic and foreign origin from 20 species, including 807 legumes and 955 grass plants are presented. The study of collection material involved in 2019 and samples received during 2015–2019 was conducted. As a result of the study of collections of forage grasses, 249 sources of valuable traits for daily growth, plant height, high yield, ripeness, resistance to diseases and pests were selected. 18 valuable samples of legumes and grasses, which were selected by economic characteristics, namely Trifolium pratense L. (5), Dactylis glomerata L. (5), Trifolium hybridum L. (4) та Festuca rubra L. (4) have been submitted for registration to the National Center of Plant Genetic Resources of Ukraine. The results of the study confirmed the high productivity of local forms of forage grasses. During 1920-2020 a search was conducted and 452 samples of perennial legumes and grasses were involved, of which 125 were legumes and 327 were grasses. Valuable starting material, which combines increased adaptive features, short growth, high productivity and feed quality of dry matter, was obtained.  Keywords: genetic resources, forage plants, preservation, sources of valuable traits, standard sample.
