Comment:
Sensitive to Ptr ToxA.
In Kulm/Erik, toxin response accounted for 24% of the variation in disease response, which was affected by 4-5 genes {10030}. Ptr ToxA is functionally identical to S. nodorum ToxA but has two predicted amino acid differences {10459}. See Reaction to Phaeosphaeria nodorum. Australian cultivars with tsn1 and Tsn1 are listed in {10540}.

Comment:
Insensitivity (disease resistance) is recessive {346}. Tsr1 {10508}, see Resistance to tanspot.
According to {10376} the same dominant allele, presumably tsn1, conferred resistance to chlorosis induced by races 1 and 3 in cultivars Erik, Hadden, Red Chief, Glenlea and 86ISMN 2137 in crosses with 6B-365.
