Comment		The Lr14 region in tetraploid wheat harbours Qlr.ubo-7B.2, a gene that confers durable resistance in durums {10734,10736} and that is present in many Italian, CIMMYT and ICARDA durum cultivars {10736}. The relationship of this gene described as Lr14c (reference genotype Creso) in {10735} remains to be determined. Reasons for considering Lr14c as a unique allele are given in {10735}. In association mapping the presence of QLr.ubo-7B.2 was predicted with 96% accuracy based on appropriate alleles of Xcfa2257.2, Xgwm344.2 and Xwmc10 in the distal region of chromosome 7BL {10736}.
