Gene Symbol detail

Gene Symbold
Class Level 1 Reaction to Puccinia triticina
Level 2 Genes for resistance
Level 3
Level 4
Symbol Wild Type Lr3
Allele Lr3aLr3bLr3cLr3d
Symbol comment Because Lr3 appears to be a complex locus {486} Democrat and Democrat/6* Thatcher should be accepted as standards. There is evidence to suggest that the allele in Mentana, and therefore many derivatives, is Lr3b {939}. If this is correct, many genotypes listed under Lr3a are likely to be Lr3b.
Comment Durum cv. Storlom likely carries Lr3a or Lr3b {10469}. Cv. Camayo was considered to have a closely linked gene, or Lr3 allele {10469}. Resistance in Storlom co-segregated with an STS derivative of Xmwg798-6B. All three Thatcher NILs with named Lr3 alleles carried the STS marker {10469}.
