AB  - As an important wheat wild relative, the P genome of Agropyron cristatum (L.) 
      Gaertn. (2n = 4x = 28) is very valuable for wheat improvement. A complete set of 
      wheat-A. cristatum disomic addition lines is the basis for studying the genetic 
      behavior of alien homoeologous chromosomes and exploring and utilizing the 
      excellent genes. In this study, a wheat-A. cristatum derivative II-11-1 was 
      proven to contain a pair of 5P chromosomes and a pair of 2P chromosomes with 42 
      wheat chromosomes by analyzing the fluorescence in situ hybridization (FISH) and 
      expressed sequence tag (EST) markers. Additionally, cytological identification 
      and field investigation showed that the 5P chromosome can weaken the homologous 
      pairing of wheat chromosomes and promote the pairing between homoeologous 
      chromosomes. This provides new materials for studying the mechanism of the alien 
      gene affecting the homologous chromosome pairing and promoting the homoeologous 
      pairing of wheat. In addition, chromosomal structural variants have been 
      identified in the progeny of II-11-1. Therefore, the novel 5P addition line might 
      be used as an important genetic material to widen the genetic resources of wheat.
