【 摘 要 】

Fourteen barley cultivars were tested through 4-year trials at Tovarnik, Nova Gradiška, Požega and Osijek sites in order to explore interaction effects of genotype by environment using AMM1 and AMM2 models for grain yield and grain protein content. The results of analysis of variance showed statistically significant effects of year, location and cultivar on grain yield and protein content. The highest grain yields had cultivars Bingo (7.357 t/ha) and Barun (7.336 t/ha). The highest values of grain protein content had cultivars Vanessa (13.06%) and Prometej (12.94%), whereas the lowest values of grain protein content were obtained for cultivars Barun (12.14%) and Princ (12.29%). High stability of grain yield and protein content, together with high level of grain yield and lower level of protein content, was estimated for cultivar Barun. The stability of cultivar Barun was more expressed in relation to the year of testing than to the location. Related to location of testing, high interaction scores (IPCA1) were obtained for cultivar Vanessa with high average protein content. Cultivars Tiffany, Plaisant and Favorit had medium to higher interaction scores (IPCA1 and IPCA2) for grain protein content, and in case of AMMI2 analysis they didn't show specific relation to locations.
