Identification of Glutenin Markers in Cultivars of three Wheat Species

Abstract

In a collection of 41 Slovak and European winter wheat cultivars (Triticum aestivum L.), 5 spelt wheat cultivars (Triticum spelta L.) and 3 durum wheat cultivars (Triticum durum DESF.) we investigated the qualitative composition of high-molecular-weight glutenin subunits (HMW-GS), the Gluten quality (GQ) score and the presence of the secale block 1B3. The highest frequency of the HMW-GS 0, 7 + 9 and 5 + 10 was found among the winter wheat cultivars. The highest GQ score of 10 was found in the cultivars SK-30 and FD-92017/1. A GQ score of 9 was found in the cultivars Astella, Ilona, Velta and MV-06-95. The HMW-GS 0 and 7 + 8, associated with a GQ of 4, were found in T. durum. The electrophoretic spectra of the spelt wheat cultivars were not homogeneous and represented 4 different lines.
