Abstract
Two genes for stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. & Henn.) resistance were transferred from the Ethiopian durum wheat ( Triticum turgidum L) accession St. 464 to Thatcher and Prelude/8 Marq uis common wheats. One gene was shown by monosomic analysis to be on c hromosome 4B and proved to be Sr7a. Monosomic analysis failed to locat e the second gene. It is only partially dominant and conditions resist ance to a range of races.
