The oat population used in this study consisted of 44 F2-derived F3 familes from a cross betwen two A-genome diploid oat species Avena altantica M66/3 x A. hirtula Cc7050-CAV4490. Markers were placed at a LOD threshold of 2.0 using MAPMAKER 3.0 with the Kosambi mapping function.
A population consisting of 150 F6 recombinant inbred (RI) lines was developed by the single-seed descent method from a cross of Kanota/Ogle. The map consists of 561 RFLP markers with 38 linkage groups, covering approximately 50% of the hexaploid oat genome. The distance between mapped RFLP markers ranged from 0.4 to 23.9 cM with an average of 5.9 cM. The marker and map data are kindly provided by GrainGenes.
