October 2018: Spring Wheat Nested Association Maps are in GrainGenes. The Spring Wheat Nested Association Mapping (NAM) population based on 2100 recombinant inbred lines from 28 families was used to construct 588 chromosome-specific genetic maps. With each population reporting ~50,000 markers, this work contributes ~1,400,000 markers to the GrainGenes collection. Many of these markers were previously entered as probes / sequences for the IWA and IWB marker collection. GrainGenes curators will be working in the coming weeks to connect these markers and fill in the data for new markers.
