Abundance
of New Varieties by Jina Martin Growers wont have a shortage of new varieties to choose from in the 2003 season. Eleven new varieties will be available for growers to try their hand at this year.
Growers need to contact their
seed suppliers early. Gorbet says. Norden is the variety
that should have the greatest amount of seed available of these six
varieties for production in 2003. Gorbet
says these varieties offer particularly good options for growers in
the southeast. These cultivars offer producers and the peanut industry some excellent variety choices for southeast conditions, he says. We should now be able to produce excellent high oleic runner peanuts in the southeast.
Andru II Andru II has excellent TSWV
resistance, equal to or better than Georgia Green, Gorbet says. Also on the disease front, this
new variety has some white mold resistance, equal to or better than
Georgia Green. This variety has good grades and high oleic chemistry.
Pod yields have been equal to Georgia Green in field tests, Gorbet says.
Andru II should be an excellent
choice for southeast production, being the most productive early maturity,
high oleic cultivar currently available, Gorbet said. Gorbet says this variety would be suitable for all peanut-growing regions. This variety has early maturity in Florida studies, but is not quite as early as Andru 93 or Virugard.
Pod yields have been equal
to Georgia Green in low TSWV pressure situations, but less where TSWV
was high, Gorbet says. GP-1 has runner
seed size and intermediate runner to spreading growth habit and early
maturity in Florida tests.
Norden has been equal to Georgia
Green in resistance to white mold, leafspot and Rhizoctonia disease,
Gorbet says.
Hull Hull is yet another variety available
for growers to combat TSWV, as well as a number of other diseases. Hull has resistance to TSWV
and late leafspot similar to C-99R, Gorbet says. It has
white mold resistance equal to or better than C-99R and better than
Georgia Green. The variety has some resistance to CBR and some root-knot nematode resistance. This later-maturing variety has jumbo runner seed size and high oleic chemistry. It is similar in seed size to C-99R, with somewhat less vine growth. Gorbet says Hull is not suitable for Oklahoma and the V-C region.
DP-1 has the highest level
of resistance to late leafspot, TSWV and white mold currently available
in a U.S. peanut cultivar, Gorbet says. We have recorded
4,800 pounds per acre pod yields in Florida tests with no fungicide
applied for leafspot control. This variety is one of the two new
UF varieties to have a normal oil chemistry. Seed size is similar to
GK 7 and Florunner. It has less vine growth than C-99R. DP-1 is a late-maturity
cultivar and is not suitable for Oklahoma and the V-C region, Gorbet
says.
When grown with recommended
or reduced pesticides, Georgia-01R was found to have a significantly
lower percentage of disease incidence, higher yield, grade and gross
dollar value return per acre compared to C-99R, Branch says. This variety has the same maturity, spreading runner growth habit and seed size as C-99R.
This variety has resulted in higher
yields, grades and dollar value returns per acre than Carver, C-99R,
Norden, Hull and
These two high oleic varieties were developed jointly with Oklahoma and the USDA, and were released jointly with the Oklahoma Agricultural Experiment Station, Simpson says. NemaTAM is the other new variety.
Tamrun OL01 is a high oleic
runner with large seed size, Simpson says. Mark Black, extension plant pathologist
at Texas A&M, says this variety is moderately resistant to TSWV
and southern blight, but is susceptible to root-knot nematodes. It has
more stress tolerance than Georgia Green. This is a high oleic Spanish variety with good yield and seed size, Simpson says. Several West Texas sites had yields above 5,000 pounds per acre in 2001 and 2002, Simpson says.
