• Red line : Bonferroni thresholds (0.5/n) Blue line : suggestive p-value (1/n) using the Genetic Type I error calculator (GEC) software (Li et al. 2012).
• Manhattan plots using qqman R package (Turner 2014).

Conclusions
Outlook
• Identification of candidate genes that are in LD with significantly associated SNPs
• Quinoa diversity panel shows a substantial variation for many agromonically important traits
which can be used in future breeding programs
• Rapid LD decay in the diversity panel indicates a weak genome-wide footprint of breeding and
selection in the history of quinoa
• Sequence variations in the associated regions can be used to develop markers for selection of
promising accessions as crossing partners to breed new varieties well adapted to European
climate conditions
• We provide tools for fast-track genetic improvement of the underutilized pseudocereal quinoa
• Similar approaches can be used to improve other orphan crops
