Spring barley genotypes traits regarding genotype : Environment interaction to Croatian environments

In field trials with four spring barley cultivars (Astor, Fran, Matej and Scarlett) during four years (2004-2007) at two localities (Osijek and Nova Gradiska) researches of grain yield, hectoliter weight, protein and starch content, extract content, friability of malt, Kolbach index and malt viscosity were carried out. Cultivar Matej (5.535 t ha-1) had significantly higher (P>0.05) grain yield in comparison with cultivars Astor 4.968 t ha-1), Fran (5.113 t ha-1) and Scarlett (5.150 t ha- 1). The year of production had significant influence on grain yield as well as on all indicators of malt quality, and differences in grain yield between localities Osijek and Nova Gradiska were not statistically justified. Significant differences between localities Osijek and Nova Gradiska in extract content and friability were estimated. Based on extract content and parameters of malt modification the best scores had cultivar Scarlett which was followed by cultivar Fran. Cultivar Scarlett had grain yield at average level of the trial, but high interaction scores (IPCA1) indicated the high adaptability of this genotype to conditions of production.
