The purpose of research - based on the study of the laws of inheritance duration of the growing season, create and submit to the state variety testing variety cocksfoot with long phases of organogenesis hay-pasovischnogo use, with productivity dry matter content of 10-11 seeds 0.6-0.7 t / ha for forest-steppe zone and Polesie. Research methods - polikros with comprehensive exploration of clones with high general combining ability (ACS). Selection work on the creation of new varieties of cocksfoot conducted 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 2014: to transfer to the state variety trials preparing high-yielding varieties cocksfoot RP-№1, which exceeded the standard by 13-15% (over 2 tsykla use - 6 years). In the competitive strain testing on the productivity of the crop exceeded the standard three numbers: RP-№1, RD-№7, Cr-№2. Yield of green mass they have made within: 29,6-28,7 t / ha; Hay 9,13-8,76 t / ha; seeds 0,27-0,26 t / ha at the level of the standard 23.9; 7.58; 0.25 t / ha, respectively, (15-16%).
