Remarks (1) Data type: Recombinant Substitution lines (RSL) between
chromosomes 1A^m^ from T. monococcum ssp. aegilopoides G1777
and chromosome 1A from the ph1b mutant of Chinese Spring (in
Chinese Spring background). The 96 monosomic-RSLs were
obtained in the absence of the ph1 gene. The centromere was
mapped by Triticum monococcum 1A telocentrics. Markers were
ordered with MapMaker (completely linked loci were merged).
(2) DS1A^m^(CS1A) is not a complete substitution of 1 A^m^.
It was recombined in the presence of Ph1b with CS distal to
XksuG34. As a result, this map can not include markers
distal to XksuG34.
(3) Short arm markers completely linked to psr161: Group A:
Xbcd762, Xcdo1188, Xpsr381, Xpsr937, Xtam52. Group B:
Xbcd446, Xbcd1072, Xbcd1796, Xpsr168, Xwg811=Xwg789,
Xcdo658. Groups A and B are separated by a spontaneous
breakpoint in 1 RSL.
(4) h = Chinese Spring allele, a = T. monococcum allele, - =
missing data or recombination 1A-1D.
