|a Aegilops variabilis (UUSvSv), an important sources for wheat improvement, originated from chromosome doubling of a natural hybrid between Ae. umbellulata (UU) with Ae. longissima (SlSl). The Ae. variabilis karyotype was poorly characterized by fluorescent in situ hybridization (FISH). The FISH probe combination of pSc119.2, pTa71 and pTa-713 identified each of the 14 pairs of Ae. variabilis chromosomes. Our FISH ideogram was further used to detect an Ae. variabilis chromosome carrying stripe rust resistance in the background of wheat lines developed from crosses of the stripe rust susceptible bread wheat cultivar Yiyuan 2 with a resistant Ae. variabilis accession. Among the 15 resistant BC1F7 lines, three were 2Sv + 4Sv addition lines (2n = 46) and 12 were 2Sv(2B) or 2Sv(2D) substitution lines that were confirmed with SSR markers. SSR marker gwm148 can be used to trace 2Sv in common wheat background. Chromosome 2Sv probably carries gametocidal(Gc) gene(s) since cytological instability and chromosome structural variations, including non-homologous translocations, were observed in some lines with this chromosome. Due to the effects of photoperiod genes, substitution lines 2Sv(2D) and 2Sv(2B) exhibited late heading with 2Sv(2D) lines being later than 2Sv(2B) lines. 2Sv(2D) substitution lines were also taller and exhibited higher spikelet numbers and longer spikes
