- Arkansas Agricultural Experiment Station
- Three new soybean varieties from the
University of Arkansas
Division of Agriculture offer producers flexible options
for varying growing conditions.
-
- "These varieties range from early Maturity group V
through Maturity Group VI," said
Pengyin Chen, soybean
breeder for the Arkansas Agricultural Experiment Station.
"There's something here for every soybean-growing area of
Arkansas."
- Foundation seed is available this year for Ozark,
Desha and Lonoke soybeans. Certified seed for Ozark will
be widely available next year, said Don Dombek,
coordinator of the U of A Crop Variety Improvement
Program.
-
- "Ozark is probably my favorite of these varieties,
because it's an early maturity soybean," Chen said. "It
grows well anywhere in the state and has very high yield
potential."

UA soybean
breeder Pengyin Chen said three new soybean varieties
released by the Arkansas Agricultural Experiment Station
will give producers more choices when planting their crops.

Ozark is an early Maturity Group V variety. In USDA Southern
Regional Uniform Group V Tests, it yielded higher than Hutcheson
and Manokin soybeans. As an experimental line, it was tested in
17 environments from 2000 to 2002 and proved to have a good
stand and resistance to shattering. Chen said it is also
resistant to several important diseases in the Mid South,
including southern stem canker, soybean mosaic virus and frogeye
leaf spot. He said it is moderately resistant to root knot
nematode and sudden death syndrome.
- Lonoke and Desha mature later than Ozark and are most
suited for the southern Delta, Chen said.
- "Mississippi producers really like Desha," he said. "And
Lonoke probably has the best disease resistance package of
these three varieties."
-
- Lonoke is a mid-Group V soybean that matures two to four
days later than Hutcheson and has higher yield potential, Chen
said. It is resistant to shattering, southern stem canker and
soybean cyst nematode. It is moderately resistant to
phytophthora root rot, races 5 and 9 of soybean cyst nematode,
reniform nematode, sudden death syndrome and frogeye leaf
spot.
-
- Desha is resistant to stem canker and soybean mosaic
virus, Chen said. "These releases add stable and
dependable soybeans to Arkansas producers' choices," he said.
