Abstract

The OS9XQ36 wheat (Triticum aestivum L.) mapping population (Reg. No. MP-2, NSL 465170) is a set of 164 F6–derived recombinant inbred lines (USDA–ARS Germplasm Resources Information Network (GRIN) accession no. GSTR 11903 through GSTR 12066) from the cross between OS9A (PI 658243), a single plant selection from the cultivar Stephens (CI 17596), and QCB36 (PI 658244), a single plant selection from the elite breeding line OR9900553. This population was developed to investigate the consistently lower grain hardness and superior end-use quality of OR9900553 compared with Stephens. This population has also been genotyped with diversity array technology (DArT) and simple sequence repeat (SSR) markers resulting in the construction of a 270-marker linkage map covering 1785 cM at a density of one marker per 7 cM. This F6–derived population is one of 20 mapping populations being used by the WheatCAP consortium (http://maswheat.ucdavis.edu/) for extensive quantitative trait locus analysis and forms part of a publicly available long-term genetic resource to map complex traits in wheat
