Heterogeneous populations is one of the ways to increase genetic diversity in varieties of self-pollinating cereals. The aim of this research was to evaluate performance of spring barley (Hordeum vulgare) composite cross population ‘Mirga’ in comparison to three homogenous varieties. Field trials were carried out during 2015–2018 under organic and conventional farming systems. ‘Mirga’ showed a tendency to be more productive under organic conditions and could be characterized as widely adaptable to various growing conditions. Net blotch (Pyrenophora teres) severity was significantly lover for ‘Mirga’ than that of checks under both conditions in most of the cases. Competitiveness against weeds for ‘Mirga’ and checks did not differ.
