Comment
Disease: Stripe rust, yellow rust.
Chen and Line (141) allocated a number of temporary designations to uncatalogued genes detected with North American P. striiformis accessions. Druchamp, Yamhill and Stephens were reported to carry 'Yr3a or Yr4a' but these genes could not be distinguished with the cultures that were used. Tests with United Kingdom isolates showed that Yamhill possessed neither of these genes (431). Sources of additional genes for seedling (designated '12') and adult resistances ('13', '14', '15') are listed in 1031.
