Sažetak
Research is based on grain yield results reached from field trials carried out with 14 winter barley varieties (Hordeum vulgare L.) during four growing seasons (2004 to 2007), at four sites (Osijek-eutric cambisol, Pozega-pseudoghley, Tovarnik-hypogley and Nova Gradiska-alluvial soil) and with two sowing densities (300 and 450 kernels per m2). Significant effects of year, locality and variety on grain yield were estimated (F=0.001). Difference between two sowing densities (300 and 450 kernels per m2) was not significant, as well as interaction variety*sowing density. Significant interactions year*sowing density, locality*sowing density, year*locality*sowing density, lokality* variety, year* variety, year* variety*lokality were found. Based on realized grain yield, variance of deviation from regression (S2di), coefficient of regression (bi) and interaction scores (AMMI1 analysis), varieties Barun, Gvozd and Prometej are suitable for more intensive conditions of growing. Higher parameters of stability and interaction scores (AMMI1 analysis) indicate that variety Bingo, which had the highest grain yield, showed favorable reactions of grain yield also in more extensive growing conditions (at lower level of production).
