Linkage map of prolamin loci Gli-D4 and Gli-D5 in hexaploid wheat

By electrophoretic analysis of F2 progenies from crosses among the hexaploid wheat varieties ‘Cajeme 71’, ‘Ablaca’, ‘Anza’ and ‘Pané 247’, two new prolamin loci Gli-D4 and Gli-D5, were mapped on the short arm of chromosome ID. The Gli-D4 locus controls gliadins of type γ and is situated on the short arm of chromosome ID between the centromere and the Gli-D1 locus with a genetic distance of 10.1±2.4 cM from this locus. The Gli-D5 locus controls gliadin type ω and was mapped 3.7 ± 0.8 cM from Gli-Dl and located between Gli-Dl and the telomere.
