Plain language summary
This article is a cultivar description for a new malting barley cultivar developed at the Agriculture and Agri-Food Canada Brandon Research and Development Centre, Brandon, MB and named AAC Goldman. AAC Goldman is a two-row, hulled, spring barley; which means that only the central spikelet is fertile (i.e. two-row) with a hard-to-remove hull (i.e. hulled) and is adapted to spring-time growing conditions across all regions of western Canada. It has higher grain yield than AAC Metcalfe (10%) and CDC Copeland (5%) which were used for comparison (i.e. check cultivars) while in the registration tests. It has good disease package of note being the leaf disease resistance (i.e. resistant to spot-form net blotch) and the moderate resistance to Fusarium head blight (a fungal disease affecting the head/spike of barley and other small cereal also known as FHB or scab) and lower accumulation of the toxin (deoxynivalenol also known as DON) produced. When tested repeatedly (i.e. over 14 site-years) in Manitoba FHB nurseries at Brandon and Portage la Prairie, AAC Goldman accumulated 35% less DON concentration than the check cultivar AC Metcalfe. In terms of quality, AAC Goldman was found to have a malting quality profile similar to intermediate between the malting checks, AC Metcalfe and CDC Copeland, and thus is recommended as malting barley. Overall, AAC Goldman has a good combination of agronomic traits, disease resistance and malting quality with lower DON accumulation being its most note-worthy feature.
AAC Goldman is a hulled, two-row, spring, malting barley (Hordeum vulgare L.) cultivar widely adapted to western Canada. It was developed from the cross TR04282/Newdale made in 2002 and was evaluated in the Western Cooperative Two-row Barley Registration Test (2010–2011) as well as the Collaborative Malting Barley Trials (2011–2012) conducted by the malting and brewing industry before being registered in 2018. AAC Goldman has a desirable combination of agronomic, malting quality, and disease resistance traits including low deoxynivalenol content.
