To enhance the economic viability of environmentally friendly farming, the genetic diversity of winter wheat should be more extensively utilized. This study aimed to evaluate and compare the grain yield, quality, and other economically important characteristics of five winter wheat varieties: ‘Brigens’, ‘Reinis’, ‘Talsis’, ‘Brencis’, and ‘Edvins’, two breeding lines, F-15176 (Produzent/06-60) and 18-94 (Ceylon/Brencis), two variety mixtures, Talsis:Brigens (M1) and Edvins:Reinis (M2) in an organic farming system. The variety ‘Skagen’ was used as a control variety. Preliminary results from one year of the study indicated that the breeding lines F-15-176 and 18–94 achieved significantly (p<0.05) higher grain yields and recorded the yield differences 1.6 and 1.1 t ha⁻¹, respectively. Grain quality traits varied considerably across all genotypes. While the variety mixtures demonstrated good winter hardiness and disease resistance, they exhibited lower yield levels compared to the standard variety.
