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 SDSPAGE, 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.
