Summary
A factor for resistance to yellow rust in the Iranian spelt wheat accession 415 was found to be located on chromosome 1B, utilizing a monosomic series of T. spelta var. saharense. Ditelosomic stocks of cv. Chinese Spring, were employed to verify the identity of the critical chromosome. The factor for resistance is most probably identical with the Yr10 allele which is also located on chromosome 1B. Moreover, the response of cv. Moro which carries Yr10 and accession 415 to 22 yellow rust races, representing a wide pathogenicity spectrum, was identical.
