Maps of the XNor region in group 1 and group 5 chromosomes

of the Triticeae genomes". Genetics 140:1367-1377.
Morphological loci were Bg (black glume) and Hg (hairy glume). The
remaining loci were mapped by hybridization of DNA probes. The Nor locus
was mapped using wheat clone pTa250.15, containing a 900 HhaI fragment from
the spacer region, including part of the promoter. Positions of the
centromeres were inferred by mapping of wheat ditelosomic stocks and T.
monococcum/wheat ditelosomic substitution lines. Loci listed on the right
are located within the adjacent vertical bars.
Comparative linkage maps of chromosome arm 1A^m^S in two T. monococcum
mapping populations and chromosome arm 1BS in mapping populations of T.
aestivum and T. turgidum. The G3116 x DV92 population of T. monococcum
comprised 74 F2 individuals, and the G1777 x G2528 population comprised
76 F3 families. The T. aestivum 1BS map was based on 91 F2 individuals
from a cross between cultivars Chinese Spring and Cheyenne. The 1BS map of
T. turgidum was based on 92 recombinant substitution lines derived from a
cross between T. turgidum ssp. durum cv. Langdon and a disomic substitution
of T. turgidum ssp. dicoccoides 1B in cv. Langdon.

Comparative linkage maps of chromosome arm 5A^S^in two mapping populations
of T. monococcum and chromosome arms 5HS and 5DS in mapping populations of
Hordeum vulgare and T. aestivum, respectively. The T. monococcum
populations are described above. The barley (H. vulgare) 5HS map was
derived from the Steptoe x Morex map published by Kleinhofs et al. The T.
aestivum 5DS mapping population comprised 45 F2 individuals from a cross
between T. aestivum cv. Chinese Spring and synthetic wheat RL5406, which
was produced from a cross of experimental line Tetracanthatch (2n = 4x =
28, genomes AABB) with Ae. tauschii.
