Sheyenne, a conventional nontransgenic soybean variety, has been
developed and released by the North Dakota Agricultural
Experiment Station.
Sheyenne, a conventional nontransgenic soybean variety, has been
developed and released by the North Dakota Agricultural
Experiment Station, according to Al Schneiter,
North Dakota State
University (NDSU) Department of Plant Sciences chair.
Sheyenne is expected to replace acreage of Barnes and LaMoure,
both NDSU-released varieties. It has good lodging resistance and
matures two days later than LaMoure and seven days later than
Barnes, according to Ted Helms, leader of the NDSU soybean
breeding program.
Helms says Sheyenne, averaged across 18 trials conducted in
North Dakota from 2004 through 2006, yielded 10 percent more
than LaMoure and 18 percent more than Barnes. Sheyenne has a
lower protein content and slightly lower oil content than the
variety Lambert. Sheyenne has a yellow hila, which is desirable
for a conventional soybean variety.
Research indicates that Sheyenne has moderate resistance to iron
deficiency chlorosis, according to Jay Goos, NDSU soil
scientist. Berlin Nelson, NDSU plant pathologist, says Sheyenne
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.
Sheyenne will be allocated through the County Crop Improvement
and Seed Association this spring. The NDSU Research Foundation
will apply for plant variety protection with Title V. Research
fees will be collected, as they have been for many years with
all NDSU soybean varieties.
The North Dakota Soybean Council provided some of the funding
for the development of Sheyenne.
