Genetic and Environmental Variation of Barley Characteristics and the Potential of Local Origin Genotypes for Food Production
The aim of this study was to evaluate the genetic and environmental variation of yield and food quality characteristics (protein, starch, β-glucan and husk content, test weight and thousand grain weight) of covered and hulless barley genotypes in organic management conditions. Two different field ex...
