Inheritance of gliadin and glutenin proteins in four durum wheat crosses

The F-2 progenies, from four crosses between landraces and commercial Portu guese durum wheat cultivars, were analysed by electrophoresis for storage p rotein composition and genetic segregation. The chromosomal location of genes was determined for gliadin and glutenin a llelic variations at the Gli-A1, Glu-A3 and Glu-A1 on 1A; Gli-B1, Glu-B3, G li-B3, Glu-B2 and Glu-B1 on 1B; Gli-A2 on 6A and Gl1-B2 on 6B. The protein patterns of landraces were uncommon and four new alleles were identified at different loci in chromosome 1 and four in the chromosome 6B (Gli-BZ). The presence of gamma -gliadin bands encoded at the Gli-B2 locus was also foun d.
