Five barley cultivars (Hordeum vulgare L.) covering a wide range in adaptation pattern, row type, growth habit and malting quality were grown in two harvest years at six agro-ecologically contrasting locations across Spain in order to study the occurrence of genotype x environment (GE) interaction for a set of malting and chicken feeding quality parameters. There was no GE interaction for the nutritional and malting characters studied, except in the case of barley protein content. The nutritional characteristics and malt extract yield showed high broad-sense heritabilities. There were significant correlations between most of the malting and feeding characters studied. In particular, extract yield and apparent metabolisable energy, the main malting and feeding characters, showed a high significant correlation. The best malting cultivars were the best feed cultivars over years and locations. Similarly, the poorest feeding cultivars were also the worst for malting, thus there is no contradiction between malting and feeding quality for either breeding or end use.
