 Muskwa is a general purpose grain barley with good disease and lodging resistance for western Canada.

Muskwa is a six-rowed, smooth-awned, hulled barley, well-adapted to the soil zones of western Canada. It is a semi-dwarf barley with strong straw, smut resistance and intermediate maturity traits equal to or better than Vivar.

Muskwa combines the desirable trait of stable grain yield across western Canada environments with a better than average combination of disease resistance reactions. Muskwa will be useful to include in rotation for scald management. The total resistance package, especially in terms of scald, compensates for a slightly lower yield than checks. The lodging resistance and smooth awns also makes Muskwa an advantageous feed/forage variety.

Strengths

  • Grain yields stable across western Canada environments.
  • Shorter (semi-dwarf) than both feed and malting checks; good lodging resistance that is better than AC Ranger, CDC Mayfair, and Tradition.
  • Percent plumps are similar to Vivar and better than AC Ranger.
  • Moderate resistant to scald, spot-form of net blotch and spot blotch; and better than Vivar.
  • Good resistance to covered (U. hordei) and false loose smut (U. nigra) similar to Vivar.
  • Test weight and 1000K wt equal to Vivar.
  • Moderate resistant to stem rust (Rpg1).
Neutral Traits
  • Yield is 4% lower than feed checks Vivar and AC Ranger.
  • Days to maturity comparable to Vivar.
  • Crude protein similar to Vivar.
  • Moderate susceptible to common root rot, similar to Vivar.
Weaknesses
  • FHB and DON reactions are similar to or worse than Vivar.
  • Moderate susceptible to net-form of net blotch; similar to Vivar.
