Divide Durum

Divide was developed by the NDSU Durum Breeding Program and released by the North Dakota Agricultural Experiment Station in 2005.  The direct parentage of Divide includes Ben and Belzer.  Divide has shown excellent yield potential in NDSU yield trials and has exchibited slightly better tolerande to FHB (Scab) than other durum varieties.

Divide durum is named for Divide county which is a consistent leader in North Dakota durum production.  Although Divide county is the Northwestern-most county in North Dakota this does not mean that the adaptation of Divide is limited to the west.  In fact, Divide performs well across the durum producing region and provides a slight advantage in the east due to its disease resistance package.

Divide is rated as moderately resistant (MR) to scab and does provide slightly enhanced protection against scab relative to other durum varieties.  However, the level of scab tolerance of Divide is not equal to that of certain hard red spring wheat varieties, but is more similar to that exhibited by the durum variety Belzer.

Divide has been given an overall quality rating of 'Excellent' by the NDSU Cereal Chemists.  The overall quality rating is based on agronomic, milling, and spaghetti processing performance.
To help ensure genetic purity, 'Divide' Durum will be protected under PVPA Title V and must be sold as a class of certified seed.
