A male-sterile T. aestivum-Ag. intermedium partial amphiploid with cytoplasm of T. timopheevii as a female parent was crossed to common wheat. The hybrid was backcrossed to the male parent several times continually and self-crossed at last. Two stable lines with common wheat phenotype, H96269-2 and H96278, have been obtained. The chromosome numbers of the two lines are all 2n = 42 in somatic cells. By inoculation test, the two lines show a high level of resistance to yellow rust. Through genomic in situ hybridization (GISH) with Ag. intermedium total genomic DNA as a probe, it is demonstrated that the two stable lines are all small segmental translocation lines, and the translocated chromosome segments from Ag. intermedium are located on the short arm terminals of wheat chromosomes. Genetics analysis suggests that the yellow rust resistance gene(s) are probably located on the translocated chromosome segments of Ag. intermedium.
