The purpose – to develop breeding technologies including the use of methods of DNA-analysis; to develop maize hybrids of different maturity groups. Methods – hybridological analysis, DNA-analysis, statistical. Results: techniques for prediction of a heterosis level, combinational ability and hybrid productivity by indices of molecular genetic markers have been developed; physiological and biochemical criteria for selection of lines by hit and drought tolerance characteristics have been determined; using lines of marker origins some hybrids have been developed. Introduction: 10 hybrids of maize – Dzhaiv, Himn, Yakhta, Feia, Etiud, Yunga, Radomyr, Top 410, Aria, Polonez were transferred to the State Variety Trial. Application sphere: research institutes of NAAS of Ukraine, agrarian and industrial complex Product Description popup.authors Соколов Вячеслав Михайлович popup.nrat_date 2020-04-02 Close
