Given the dramatic rise in high‐cannabinoid hemp (Cannabis sativa L.) production in the
last decade, there is an increasingly urgent need to characterize available germplasm and
develop knowledge to accelerate the breeding of uniform and stable cultivars. Despite
persistent cultivation of hemp cultivars for grain and or fiber around the world, the diversity
and genetic underpinning of key traits for breeding and cultivation are poorly understood.
For 30 high‐cannabidiol hemp cultivars replicated on two field sites, we sought to evaluate …
