--------------------
Originally temporarily designated SrR (Anugrahwati et al. 2008), this Imperial rye-derived resistance gene is located in an interstitial translocation on chromosome 1DS. Preliminary data suggest that recombination with Sr33 on 1DS to form a linkage block is not feasible (Lagudah et al. unpublished), but coupling with Sr45 or other recently identified resistance genes on 1DS may be possible. Sr50 could be an allele of Sr31, but has different race specificity and is contained in a different rye translocation. A further specificity involves the SrAmigo gene present in a 1AL.1RS translocation present in some plants of Amigo and again, the allelic status of this gene is unknown.
