Comment

Associated with adult plant resistance to a mixture of six Pt races (MHDSB, MFPSB, MLDSB, TBBGJ, TFGJQ, and TFBGQ in Crookston, MN field in 2012 and with Pt race BBBQJ in Ciudad Obregon, Mexico field in 2013.

Curator Note (VCB, 04/2019). QTL names and markers associated with this QTL are from two sources, the primary reference and information embedded in the QTL track of the GrainGenes genome browser for the Triticum turgidum ssp. durum cv. Svevo (RefSeq 1.0) assembly. QTL were initially curated by members of the International Durum Genome Sequencing Consortium who assigned the encoded QTL name and information on the assembly including computationally-aligned significant markers (SNPs, DArTs, SSRs). To curate this QTL for GrainGenes, the primary reference was reviewed, the original QTL name was synonymized, and original markers were added to the significant marker list shown on the QTL report page. GrainGenes users are advised to review the qtl track in the Svevo assembly for additional position information and confidence intervals, as well as the primary reference for additional statistics.
