<jats:p> Alloplasmic euploid wheat with the cytoplasm of Elymus ciliaris (2n = 4x = 28, S<jats:sup>c</jats:sup>S<jats:sup>c</jats:sup>Y<jats:sup>c</jats:sup>Y<jats:sup>c</jats:sup>) is male sterile and has reduced vigor. However, alloplasmic plants with E. ciliaris chromosomes 1S<jats:sup>c</jats:sup> or 1Y<jats:sup>c</jats:sup> marked by gliadin genes Gli-S<jats:sup>c</jats:sup>1 and Gli-Y<jats:sup>c</jats:sup>l, respectively, are vigorous and fertile. The Rf genes on 1S<jats:sup>c</jats:sup> and 1Y<jats:sup>c</jats:sup> are named Rf-S<jats:sup>c</jats:sup>1 and Rf-Y<jats:sup>c</jats:sup>1. Two chromosome translocations involving 1Y<jats:sup>c</jats:sup> were isolated. The first involved the short arm of 1Y<jats:sup>c</jats:sup> translocated to the short arm of wheat chromosome 3B. The second involved the short arm of 1Y<jats:sup>c</jats:sup> translocated to the short arm of a chromosome, designated L, of E. ciliaris. The second line also has another E. ciliaris chromosome designated A and lacks wheat chromosome 6A. This line is resistant to Puccinia recondita. The relationship between fertility restoration and nucleolar organizing regions is discussed. Key words : Triticum aestivum, Elymus ciliaris, chromosome addition, Rf genes, nucleolar organizing regions. </jats:p>
