Grenora was developed by the NDSU Durum Breeding Program and released by the North Dakota Agricultural Experiment Station in 2005. The direct parentage of Grenora includes two NDSU experimental lines. Grenora durum is named for the northwest North Dakota town of Grenora. Grenora is well-adapted to the entire durum producing region of North Dakota.
Grenora has shown excellent yield potential in NDSU yield trials as well as very good yield stability across multiple environments. Grenora matures slightly earlier than other durum varieties rated as medium for maturity, specifically about 1 to 2 days earlier than 'Divide'.
Grenora has been given an overall quality rating of 'Good' by the NDSU Cereal Chemists. The overall quality rating is based on agronomic, milling, and spaghetti processing performance.
To help ensure genetic purity, 'Grenora' Durum will be protected under PVPA Title V and must be sold as a class of certified seed.
