Resistance Genes

Sr12 is effective against all stem rust races in Australia and is present in several wheats eg., Gregory, LRPB Impala

Sr36 is effective against all stem rust races in Australia and is present in several wheats eg., Lancer, Reliant

Sr30 is effective against all stem rust races in Australia and is present in several wheats eg., Dollarbird, Hartog, Batavia, Houtman

Sr45 is effective against all stem rust races in Australia and is also effectve against Ug99 but not has been used in wheat varities

Sr33 is effective against all stem rust races in Australia and is also effectve against Ug99 but not has been used in wheat varities

Sr39 is effective against all stem rust races in Australia and is also effectve against Ug99 but has not been used in wheat varities

Sr32 is effective against all stem rust races in Australia and is also effectve against Ug99.

Effective against all pgt isolates in Australia but has not been used in breeding. Introgressed as a 2S translocation which also carries Sr32 (on 2DS). Recombinants which have separated SrAest1t from Sr32 have been produced.

Sr50 is effective against all stem rust races in Australia and is also effectve against Ug99. However, virulence has been found in Kazakhstan recently. Originally introgressed into wheat from rye but was assocaited with stcky dough character. However, recombinants with shortened rye segment without sticky dough caharacter as 1DL/1RS are now available

Transferred to wheat as a translocation on chromosome 6D. Previously known as SrB. Effective against all stem rust pathypes in Australia. The genes has been cloned and available as a non-recombogenic fragment which harbours Sr61 and Sr26
