Genome-wide association study (GWAS) identifies genetic loci controlling Distinctness, Uniformity, and Stability (DUS) traits in wheat.

ABSTRACT:

Key message

Genetic analysis of wheat Distinctness, Uniformity, and Stability (DUS) characteristics identifies significant marker-trait associations for 15 DUS traits, including associations for 'seed: colouration with phenol' closely linked to Ppo-A1. Crop improvement via breeding underpins the yield gains required for future food security. Commercial development of new varieties is supported by the legal protection afforded by Plant Variety Rights, which for wheat is awarded via evaluation of 27 morphological 'characteristics' as part of Distinctness, Uniformity, and Stability (DUS) testing. While identification of molecular markers predictive for wheat DUS characteristics would be useful to aid processes such as variety identification and DUS test optimization, little is known a
