Divide, a New Durum Variety From North Dakota Agricultural Experiment Station

Divide is the third new durum variety that the North Dakota Agricultural Experiment Station developed and released this spring, according to Al Schneiter, North Dakota State University Department of Plant Sciences chair.

Divide is a cross between the varieties Belzer and Ben that had been crossed with an experimental line. Other varieties in its parentage include Vic, Rugby, Regold, Ward and a number of other experimental lines. The NDSU greenhouse cross was made in 1994, according to Elias Elias, leader of the NDSU durum breeding program.

When compared with the variety Mountrail at a number of North Dakota Research Extension Centers and during several growing seasons, Divide has a 1-bushel-per-acre yield advantage over Mountrail. Divide has a higher test weight and a larger kernel size than Mountrail.

The straw strength and plant height of Divide is about equal to that of Mountrail. Divide has a slightly higher resistance to fusarium head blight and leaf diseases than Mountrail.

Divide has similar end-use qualities as Belzer, according to Frank Manthey, director of durum quality research at NDSU. When compared with Mountrail and Lebsock, Divide has higher semolina protein content and much stronger dough properties. Pasta made from Divide has better color than Mountrail and greater cooked firmness than Lebsock or Mountrail.

Divide is named after Divide County, a major durum production area in northwestern North Dakota. Divide will be allocated through the Country Crop Improvement Associations next spring. The NDSU Research Foundation will apply for plant variety protection with Title V and assess research fees of 25 cents per bushel on registered and certified seed.
