The objective of research was to determine grain yield, hectoliter weight, grain proteins and starch content of 17 winter barley cultivars from trials at four locations (Tovarnik, Nova Gradiska, Pozega and Osijek) and during three years (2002 to 2005). All traits were significantly influenced by year (Y), location (L) and genotype (G) while sowing rate (300 and 450 seeds per m 2 ) and genotype*sowing rate (G*D) did not affect trait means (P>0,05). Interactions as year* sowing rate (Y*D), location*sowing rate (L*D) and year*location*sowing rate caused significant influence to grain yield and proteins and starch content in grains. Regression coefficient “bi”, ecovalence “W i ” and variance of deviations from regressions “S 2 d i ” pointed out best performance of cultivars Barun, Bingo and Gvozd in more intensive growing conditions due to its top yielding, lowest proteins and rich starch content of grains. Opposite to this, best yield and quality performance of cultivars at low input production could be expected from cultivars Plaisant, Vanessa, Favorit, Lord and Heraklo.
