Abstract

The prolamins (glutenins and gliadins) are the most important quality components in wheat. In this study, the genetic variability for prolamins in a collection of 158 Spanish durum wheat landraces (Triticum turgidum L ssp durum, 2n = 4x = 28, AABB) has been stablished. The allelic variability for Glu-A1, Glu-B1, Glu-A3, Glu-B3 and Glu-B2 loci was analyzed by protein electrophoresis. The Glu-B1 was the most polymorphic HMW-GS locus, while the Glu-B3 was the most polymorphic LMW-GS locus, with seven and twelve alleles respectively. Based on the different electrophoretic mobility observed in SDS-PAGE, novel subunits or subunit combinations have been described for almost all loci. After the genetic characterization, a quality analysis was performed on 116 landraces, in order to study the effects of the glutenin and gliadin alleles from different loci on quality.
