 Lowe is a malting barley with:
  • Low DON accumulation, averaging 50% less than AC Metcalfe
  • Grain yield is 12% higher than AC Metcalfe and 6% higher than CDC Copeland
  • Promising malt quality for craft brewing with low protein and high extract

Strengths of Lowe
  • Consistently low DON levels, up to 85% lower than AC Metcalfe. Lowe has a better than average reaction to FHB, as noted by the Prairie Recommending Committee for Oat and Barley.
  • Grain yields are 12% higher than AC Metcalfe and 6% higher than CDC Copeland across Western Canada.
  • Lodging scores are lower than the malting checks and similar to Xena.
  • Good malting traits with high kernel weight and low protein. FAN equal to CDC Copeland and less than AC Metcalfe. Fine extract is higher than the malting checks AC Metcalfe and CDC Copeland. Peeling and wort β-glucan levels are lower than the checks in Coop trials.
  • Higher percent plumps, similar test weight, and heavier kernel weight compared to the malting checks.
  • Disease resistance: resistance to the surface-borne smuts, loose smut, scald and spot-form net blotch is better than the malting checks.
