Abstract
Restriction-fragment-length polymorphism maps of chromosomes 6A, 6B and 6D of hexaploid wheat (Triticum aestivum L. em. Thell) have been produced. They were constructed using a population of F`7-8` recombinant inbred lines derived from a synthetic wheat x bread wheat cross. The maps consist of 74 markers assigned to map positions at LOD greater than or equal to 3 (29 to 6A, 24 to 6B and 21 to 6D) and two 6D markers ordered at a LOD of 2.7. Another 78 markers were assigned to intervals on the maps. The maps of 6A, 6B and 6D span 178, 132 and 206 cM, respectively. Twenty-one clones detected orthologus loci in two homoeologues and three detected an orthologous locus in each chromosome. Orthologous loci are located in intervals of from 1.5 to 26 cM throughout 70% of the length of the linkage maps. Within this portion of the maps, colinearity (homosequentiality) among the three homoeologues is strongly indicated. The remainder of the linkage maps consists of three segments ranging in length from 47 cM to 60 cM. Colinearity among these chromosomes and other Triticeae homoeologous group 6 chromosomes is indicated, and a consensus RFLP map derived from maps of the homoeologous group 6 chromosomes of hexaploid wheat, tetraploid wheat, T. tauschii, and barley is presented.
