Development and Characterization of Wheat-Agropyron cristatum Introgression Lines Induced by Gametocidal Genes and Wheat ph1b Mutant

The P genome of Agropyron cristatum Gaertn. contains many desirable genes that can be utilized as genetic resources to improve wheat. In this research, we used both the gametocidal chromosome 2Cc and pairing homologous gene (Ph1b) mutant induce structural aberrations translocations between wheat 4P, 5P, 6P chromosomes. By using two approaches, a total 19 wheat-A. have been identified, in which 13 were induced by Triticum aestivum cv. Chinese Spring (CS) ph1b (CS ph1b) six from Aegilops cylindrica Host. wheat-4P, -5P -6P A. characterized situ hybridization set conserved orthologous (COS) molecular markers. included centromeric translocations, terminal dicentric deletions. average induction frequency was 10.9% 8.8% mutant. highest obtained for 4P approaches. All translocation lines valuable identifying related genes. addition, these provided new germplasm accessions improvement
