Description

Spring two-row
MT124112 is a spring, 2-row, hulled barley developed for malt barley production in Montana. MT124112 has a lax head type, rough awns, white aleurone and long rachilla hairs. 

Across all environments, MT124112 has substantially lower protein than the top performing malt varieties grown in Montana. When MT124112 is compared to commonly grown lines, plump percentage and test weights are higher; heading dates are earlier while maturity dates are later; plant heights are shorter and less prone to lodging under irrigation. Earlier heading dates and later maturity date increases time of grain fill by about five days. The average yields of all lines reported are essentially equal when grown under the conservative nitrogen applications of malt barley production. However, MT124112 features a gene that consistently maintains malt-appropriate levels of grain protein under high fertilizer, thus displaying a substantially higher yield potential.
*See pertaining data in variety release document.
Agronomic Characteristics Yield: Higher with higher test weights and percentage plump seed
Protein: lower than average, consistently lower in dry land and with higher N applications
Maturity: Earlier heading dates and later maturity than other common MT varieties
Straw Strength: Midstrong
Straw Length: Shorter and less prone to lodging under irrigation
Disease Reaction: Since 2015, trials have not had consistent disease pressure for disease scoring, although occasional observations of rust and leaf spots occur in Sidney under irrigation. We have ongoing trials in Sidney and North Dakota evaluating fusarium infections with subsequent DON (deoxynivalenol) testing by North Dakota State University. Not surprisingly, MT124112 responds to head blight similarly to Hockett.
Malting Characteristics

The malt quality of MT124112 is suitable for both all-malt brewing as well as adjunct brewing. Generally, malting traits are either statistically equal or superior in performance according to the criteria determined by the American Malting Barley Association (AMBA). These traits stay within the acceptable ranges when grown under dryland or irrigated conditions.

Quality Strengths:

  • High malt extract
  • Low β-glucan
  • Faster hydration
  • More stable quality across variable growing conditions
