Table 1. Summary of the polymorphic markers integrated in to the 21 chromosomes based on 158 recombinant inbred lines derived from a cross between two spring wheat cultivars, ‘Cutler’ x ‘AC Barrie’.

Chromosome 2A, 3A, 3B, 5A and 7B each has two linkage groups.

Linkage group	Total number of mapped markers	Total map length (cM)	No. of markers used for mapping	Map length used for mapping (cM)	Mean map distance/Marker
