Wheat Wheat leaf rust All stage resistance
Lr23
Last updated: 10/29/2024
Lr23 is widely used in Australian durum and bread wheats. Virulence is present but the gene can still provide effective resistance in combination with other genes
Wheat Wheat stem rust All stage resistance
Sr12
Last updated: 11/15/2023
Sr12 is effective against all stem rust races in Australia and is present in several wheats eg., Gregory, LRPB Impala
Wheat Wheat stem rust All stage resistance
Sr36
Last updated: 11/15/2023
Sr36 is effective against all stem rust races in Australia and is present in several wheats eg., Lancer, Reliant
Wheat Wheat stem rust All stage resistance
Sr30
Last updated: 11/15/2023
Sr30 is effective against all stem rust races in Australia and is present in several wheats eg., Dollarbird, Hartog, Batavia, Houtman

Sr45
Last updated: 11/05/2024
Sr45 is effective against all stem rust races in Australia and is also effectve against Ug99 but not has been used in wheat varities

Wheat Wheat stem rust All stage resistance
SrAes1t
Last updated: 11/15/2023
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.
Wheat Wheat stem rust All stage resistance
Sr50
Last updated: 11/08/2024
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
