The object of study - selection of red fescue (Festuca rubra L.) and meadow grass (Poa pratensis L).). The purpose of research - based modeling using new varieties of genes to create and pass on state testing varieties of grass-roots of grasses - red fescue and meadow grass for pasture grass i use with the productivity of dry matter, respectively, 9.10 and 8.9 and 0.6 seeds -0.65 and 0,40-0,45 t / ha for the conditions of forest-steppe i Polesie. Research methods - polikros with comprehensive exploration of clones with high general combining ability (ACS). Selection work on the creation of new varieties of red fescue and meadow grass is carried out in full breeding scheme. Starting material was prepared by the method of reciprocal hybridization using varieties of different ecological and geographical origin. The main results for the year 2011: a hotbed of hybridization, hybrid breeding nurseries and most productive was the number of red fescue, tentatively titled Zorya, which provided an increase of hay 2.5 t / ha (21.8%) at the level of the standard 9.3 t / ha . Significantly exceeded the standard for seed yield 8 nomerіv, in which the level of productivity of seeds and increase it over the standard were respectively: 0.38 (1.2 i 0.43 t / ha), 023 (1.18 i 0.41 t / ha ), 040 (1.18 i 0.41 t / ha), Zorya (1.14 i 0.37 t / ha), 016 (1.13 i 0.36 t / ha), 033 (1.09 i 0.32 t / ha), 021 (1.08 i 0.31 t / ha), 015 (1.02 i 0.25 t / ha). Based on the isolation and study in breeding nurseries three numbers (01.10.01, 02.10.01 10.01.28 i) cultivar meadow grass on the preliminary title Neos, the practical use of which will significantly simplify the technology of seed cleaning and thereby achieve significant ekonomicheskogo effekta seed this culture.
