Introgression of the Triticum timopheevii Genome Into Wheat Detected by Chromosome-Specific Kompetitive Allele Specific PCR Markers.

ABSTRACT: Triticum timopheevii (2n = 28, A ^t A ^t GG) is a tetraploid wild relative species with great potential to increase the genetic diversity of hexaploid wheat Triticum aestivum (2n = 42, AABBDD) for various important agronomic traits. A breeding scheme that propagated advanced backcrossed populations of wheat-T. timopheevii introgression lines through further backcrossing and self-fertilisation resulted in the generation of 99 introgression lines (ILs) that carried 309 homozygous segments from the A ^t and G subgenomes of T. timopheevii. These introgressions contained 89 and 74 unique segments from the A ^t and G subgenomes, respectively. These overlapping segments covered 98.9% of t
