Complete linkage occurred for a derived STS marker Xorw1 and Pch1 in a Coda/Brundage RIL population and the marker identified the presence or absence of Pch1 among 44 wheat accessions{10513}

Comment
|
Pch1 is closely linked with Ep-V1 {973}. Delibes et al. {236} concluded that Pch1 was not located in chromosome 7D whereas Law et al. {776} found that H-93-70 possessed a unique allele, Ep-D1b, in common with VPM1 and its derivatives. Eyespot resistance and Ep-A1b in chromosome 7A were genetically associated {704}.
