Abstract Tetraploid Thinopyrum elongatum is a valuable source of genes useful for improving the resistance wheat to diseases such as stripe rust, powdery mildew, and Fusarium head blight. There an urgent need new tetraploid Th. disease that can be transferred via alien translocation lines. We previously reported chromosome 4E (4D) substitution line carries all-stage rust genes. To optimize utility these in breeding programs, we developed lines by inducing chromosomal structural changes through 60Co-γ irradiation developing monosomic In total, 53 plants with different were identified. Three homozygous (T4DS·4EL, T5AL·4EL, T3BL·4EL) addition (T5DS·4EL) identified on basis GISH, FISH, FISH-painting, 55K SNP array analyses. These four lines, which contained 4EL, exhibited enhanced resistance. Thus, gene (tentatively named Yr4EL) was localized 4EL elongatum. By examining diploid genome, 48 SSR markers specific obtained, 32 co-segregated 4EL. Furthermore, 4DS·4EL had better agronomic traits than parents. After transferring Yr4EL into cultivars SM482, CM42, SM51, derived progenies diverse genetic backgrounds, but they all resistant there no yield penalties. may varieties rust.
