Winter barley selection in steady grain production provision in the central forest-steppe of Ukraine

Abstract

Identification of genetic stability and adaptation of crops varieties, including winter barley is rather important for breeding programs. The paper reveals the results of long-term (2003/2004 – 2015/2016) winter barley studies conducted in Myronivka Institute of Wheat named after V.M. Remeslo, NAAS of Ukraine. The level of winter barley yields manifestation depending on the varying weather conditions of vegetation in the ForestSteppes of Ukraine was determined. It was proved that the use of AMMI and GGE biplot models made it possible to carry out profound estimation of genotype-environment yield interaction for winter barley genotypes under different seeding time and select the best ones in terms of yield and breeding lines stability.
