Sheyenne
A conventional, nontransgenic soybean, Sheyenne is expected to replace acreage of Barnes and LaMoure, both NDSU-released varieties. Sheyenne has good lodging resistance and matures two days later than LaMoure and seven days earlier than Barnes.
Sheyenne yielded 10 percent more than LaMoure and 18 percent more than Barnes in 18 trials conducted in North Dakota from 2004 through 2006. Sheyenne has a lower protein content and slightly lower oil content than the variety Lambert. Sheyenne also has a yellow hila, which is desirable for conventional soybean varieties.
Research indicates that Sheyenne has moderate resistance to iron deficiency chlorosis and has resistance to Phytophthora root rot Race 3 and is segregating for resistance to Race 4.
Sheyenne is named after the Sheyenne River that meanders through central and eastern North Dakota.
