AB  - Thinopyrum ponticum (2n = 10x = 70) is a wild relative of wheat with high 
      tolerance to both biotic and abiotic stresses; it has been wildly used in wheat 
      genetic improvement. A disomic substitution line named SN19647 was derived from a 
      cross between Triticum aestivum and the wheat-Th. ponticum partial amphiploid 
      SNTE20 (2n = 8x = 56). It was evaluated for disease resistance and characterized 
      via sequential fluorescence in situ hybridization (FISH)-genomic in situ 
      hybridization (GISH) and molecular markers. The results showed that SN19647 
      carried resistance to both powdery mildew and leaf rust. It contained 42 
      chromosomes with a pair of wheat chromosome 1B replaced by a pair of J(S) 
      chromosomes from Th. ponticum. In addition to chromosomal substitution events, 
      structural variation also occurred on wheat chromosomes 2A, 5A, 6B, and 7B. Based 
      on marker analysis, 19 markers specific to the J(S) chromosome were obtained, of 
      which seventeen markers belonged to homoeologous group one. These results 
      indicated that SN19647 was a 1J(S) (1B) substitution line. Compared with the 
      known 1J(S) (1D) substitution line CH10A5, it was found that 17 markers generated 
      different specific bands to Th. ponticum, confirming the novelty of the 1J(S) 
      chromosome in SN19647. Therefore, SN19647, resistant to powdery mildew and leaf 
      rust, was a novel 1J(S) (1B) substitution line that can be used in wheat genetic 
      improvement.
