CDC MEREDITH 40 Two-rowed, a cross of SM98472/SM98787, registered in 2008, and was developed by the Crop Development Centre, University of Saskatchewan. TM AGRONOMIC TRAITS • Higher yield than AC Metcalfe • Low grain protein • Mature two days later than AC Metcalfe • Fair resistance to lodging • Resistant to true loose smut • Moderately resistant to stem rust, Fusarium head blight, covered smut, false loose smut and black semi-loose smut MALTING QUALITY TRAITS • Extract similar to or higher than AC Metcalfe • S/T higher than average • Color higher than AC Metcalfe • Enzyme levels similar to AC Metcalfe • Beta-glucan higher than AC Metcalfe BREWING QUALITY TRAITS • Good overall brewhouse performance • Higher extract • Lautering time similar to AC Metcalfe • Excellent fermentability • Good foam stability and physical stability • Slightly higher beer colour OVERALL COMMENTS CDC Meredith represents a variety with significantly improved yield potential. Quality attributes similar to Harrington, AC Metcalfe and CDC Kendall, but most importantly it consistently offers lower grain protein and increased malt extract.

CDC POLARSTAR Two-rowed, a cross of OU1003/CDC Kendall, registered in 2008, and was developed by the Crop Development Centre, University of Saskatchewan and Sapporo Breweries. AGRONOMIC TRAITS • Yield similar to CDC Kendall • Fair resistance to lodging • Maturity is earlier than AC Metcalfe • Moderately resistant to Fusarium head blight • Fair resistance to covered smut, false loose smut and black semi-loose smut • Very susceptible to true loose smut TM MALTING QUALITY TRAITS • Malting profile similar to CDC Kendall • Higher enzymes • Higher Extract • Produce Lox-less malt • Higher soluble protein • Average beta-glucan BREWING QUALITY TRAITS • Satisfactory overall brewhouse performance • Very fast conversion time • Faster lautering than AC Metcalfe • Good yield and material efficiencies • The LOX-less trait positively effects beer foam retention and beer flavor stability (less oxidation) OVERALL COMMENTS The LOX-less trait positively effects beer foam retention and beer stability thus increasing shelf life and transportability of the product. CDC Polarstar has much higher diastatic power, which would make it very suitable where higher levels of adjuncts are used in brewing. In addition, the improved husk retention helps during lautering by aiding in the formation of a better filtration bed.
