ResumenHordeum chilen e Roem. et chultz. is a wild barley species with potential in cereal breeding. lndeed hexaploid tritordeum, which is being commercialized at present dueto its differential attribute compared to common wheat, is the amphiploid derived from the cross between H chilen e and durum wheat (Martin and Sánchez-Monge 1982). Besides, H chilense has also potential in wheat breeding for important traits such as seed carotenoid content (Mattera et al. 20lSa· Mattera et al. 2015b). Gene~c studies ,ha ve allow~d the identification and mapping of candidate genes for quality traits ~o~guez-Suar.ez and Atlenza 2012; Rodríguez-Suárez and Atienza 2014) but the diversity wlthin the specles .has not been fully exploited. In this context, the availability of highthro~ put genotypmg platform~ constitutes an important tool for genetic studies in H chilense.
