Molecular and physical characterization of grain hardness in European spring common wheat (Triticum aestivum L.).

ABSTRACT: Grain hardness is the single most important trait in determining technological properties and end-use quality of wheat product. This trait is controlled by two genes (Pina-D1 and Pinb-D1) at the Hardness (Ha) locus. Soft endosperm kernels are characterized by the presence of alleles 'a' in both genes (Pina-D1a and Pinb-D1a), while the medium hard and hard grain is the result of deletion in the Pina-D1 gene or single mutation of the Pinb-D1 gene. The aim of the current study was to determine the relationship between common wheat grain hardness and the presence of puroindoline genes. Eighty-one spring common wheat cultivars from Europe were analysed for grain hardness by SKCS (Single Kernel Characterization System) and Pin-D1 genes. The
