Effect of genotype and environment on wheat quality in VCU trials

Three winter wheat standard genotypes (Žitarka, Srpanjka and Divana) were grown in VCU trials on two locations (Osijek and Zagreb) during five years (2010-2014). Influence of genetic and environment conditions of locations on wheat quality components (protein content, sedimentation value and wet gluten content) were investigated. In a combined analysis of variance, effect of genotype, environment, and their interaction (GEI) were highly significant for all analyzed traits. All the three traits were influenced more by the year than by the location. Genotype by environment interaction were analyzed by AMMI model and the results are presented by AMMI1 and AMMI2 biplot. Over all environments in average the highest protein content (15.48%) and sedimentation value (52.98 cm³ at 14 % moisture) had genotype Divana which also had the highest interaction level according to AMMI1 biplot, while genotype Žitarka had highest wet gluten content (41, 05%). In this investigation Osijek location was favorable for investigated quality traits of protein and wet gluten content.
