Abstract

© 2019 Crop Science Society of America. All rights reserved. The Triticeae-CAP spring wheat nested association mapping population (Reg. No. MP-10, NSL 527060 MAP) consisting of recombinant inbred line (RIL) populations derived from 32 spring wheat (Triticum aestivum L.) accessions each crossed to a common spring wheat parent, ‘Berkut’, has been released. The spring wheat accessions consisted of 29 landraces and three cultivars. Each population consists of approximately 75 lines for a total of 2325 RILs (Reg. Nos. GSTR No. 14701–GSTR 17133). The RILs have all been genotyped with the Illumina wheat iSelect 90K single nucleotide polymorphism array using the Infinium assay method and through genotype-by-sequencing. This nested association mapping population provides a genotyped germplasm resource for the wheat community. A potential strategy for use of the material is to screen the parents for a trait of interest, followed by analysis of RIL of populations that are likely to be segregating for a target trait or sequence.
