Abstract
The Finch‐Eltan winter wheat (Triticum aestivum L.) recombinant inbred line (RIL) population (Reg. No. MP‐11, NSL 528074 MAP) was developed by Washington State University from soft white winter wheat cultivars ‘Finch’ and ‘Eltan’. This population of 155 RILs was developed by single seed descent from the F2 generation to the F5 generation. It was genotyped using the 9k iSelect single nucleotide polymorphism (SNP) chip, simple sequence repeat markers, and 90k iSelect SNPs. A total of 1258 markers were polymorphic and were mapped to 21 linkage groups that locate to 15 of the wheat chromosomes. The population has been phenotyped to study the genetics of freezing tolerance, snow mold tolerance, stripe rust resistance, straw residue breakdown, and Cephalosporium (Cephalosporium gramineum) stripe resistance. Markers were identified that are closely linked to quantitative trait loci (QTL) that influence these traits, and there is potential for this population to be used to detect QTL for other traits. Because the parents are elite breeding lines developed for the US Pacific Northwest, this population is particularly well‐suited to facilitating breeding efforts in this region.
