Origin & Breeding History: 'Montana' originated from a cross between 'E 99/73/126' and 'E 99/89/130', conducted in 2004 in Ebstorf (Lower Saxon), Germany. One of the progeny designated as, 'Montana' was identified in 2006. Selection was based on positive agronomic criteria.

Tests & Trials: The comparative trial for 'Montana' was conducted by Global Agri Services Inc. during the 2018 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row containing 70 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean difference was significant at the 5% probability level based on a paired Student's t-test.
