ABSTRACT
Resistance based on single recessive tan spot HST insensitivity genes (tsn1, tsc1, tsc2) and tan spot resistance genes (tsr2 to tsr5) (Faris et al., 2013) and QTLs conferring quantitative resistance to different races e.g located on chromosomes 1BS and 3BS and being effective against Ptr races 1, 2, 3 and 5 are known (Faris and Friesen, 2005). Furthermore, tsn1 has been isolated (Faris et al., 2010). Additional sources of resistances were identified in wheat and in related wild species, wheat-alien species derivatives and synthetic hexaploid wheat lines (Faris et al., 2013).
