Abstract: Abstract: Hybridization between Wheat-rye disomic substitution is an important way to induce wheat-rye translocation, which has important theory value and practical significance. In this study, DS1R/1D and DS5R/5A, DS6R/6A was hybridized. The results showed that F1 had 19 bivalents and 4 univalents in meiosis, homoeologous chromosome pairing and chromosome translocation phenomenon appeared;In F2,24 common wheat types with rye traits plants were detected by genome in situ hybridization and obtained 10 plants with chromosomal translocation, and the translocation frequency was 41.6%. Translocation lines was 06-16-7,06-16-3,06-16-5,06-16-7,06-16-8,06-17-7,0617-11,06-17-15,06-17-16 and 06-18-5,respectively. Because parent selection and testing plant had a definite purpose, translocation plants could have a practical applications.
