Wheat-rye 1BL.1RS translocations have been widely used in wheat breeding programs. A 1BL.1RS translocation wheat line, 91S-23, was developed from a 1R monosomic addition of the rye (Secale cereale) inbred line L155 into wheat (Triticum aestivum) MY11. A new commercial wheat cultivar, CN18, which also contained the 1BL.1RS translocation, was derived from the cross MY11 × 91S-23. Polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) indicated that the rye centromere was eliminated from the 1BL.1RS chromosomes of CN18 but not from 91S-23. Based on the 1RS source and the centromeric structure of the translocation chromosome, CN18 qualifies as a new wheat cultivar possessing a 1BL.1RS translocation. CN18 displayed high yield performance and resistance to powdery mildew and stripe rust, whereas 91S-23 was susceptible to these diseases. The present study provides a new 1RS resource for wheat improvement.
