Linkage relationships between prolamin genes on chromosomes 1A and 1B of durum wheat

Gliadin and glutenin electrophoresis of F₂ progeny from four crosses of durum wheat was used to analyse the linkage relationships between prolamin genes on chromosomes 1A and 1B. The results showed that these genes are located at the homoeoallelic lociGlu-1,Gli-3,Glu-3 andGli-1. The genetic distances between these loci were calculated more precisely than had been done previously for chromosome 1B, and the genetic distances betweenGli-A3,Glu-A3 andGli-A1 on chromosome 1A were also determined. Genes atGli-B3 were found to control some-gliadins and one B-LMW glutenin, indicating that it could be a complex locus.
