January is a busy month for meetings and getting updates on what is new in peanut production. The Colquitt County Peanut Production meeting was held a couple of weeks ago and I have been getting a question or two about the information that Scott Monfort and Mark Abney provided area peanut growers.
Do you have information on other varieties? Below is information about various peanut varieties from the UGA Peanut Production Guide and the Quick Guide.
AUNPL-17 is a new high-yielding, high-oleic, TSWV-resistant, runner-type peanut cultivar that was released in 2017 by Auburn university and The USDA Peanut Lab in Dawson, GA. AUNPL-17 is a medium maturing (140 to 145 days), medium sized seed, runner-type cultivar.
GEORGIA 16HO is a new high-yielding, high-oleic, TSWV-resistant, large-seeded, runner-type peanut cultivar released by the Georgia Agricultural Experiment Station in 2016. Georgia 16HO also has a large runner seed size similar to two other large-seeded, high-oleic, runner-type varieties, Florida-07 and TUFRunner ‘727’.
GEORGIA 18RU is a new high-yielding, normal-oleic, TSWV-resistant and leaf scorch-resistant, medium-large seeded, runner-type peanut cultivar released by the Georgia Agricultural Experiment Station in 2018. Georgia-18RU combines high yield, high grade, high dollar value, TSWV resistance, and leaf scorch resistance with the desirable normal-oleic trait for peanut butter manufacturers.
GEORGIA 20VHO is a new high-yielding, high-TSMK grading, very high-O/L ratio, TSWV-resistant, runner-type peanut cultivar released in 2020 by the Georgia Agricultural Experiment Stations. Georgia-20VHO has higher percentage of total sound mature kernel (TSMK) grade compared to several other high-oleic runner varieties in Georgia. Georgia-20VHO combines high-yield, grade, and dollar values with TSWV-resistance and very high-O/L ratio for longer shelf-life of peanut and peanut products.
TifNV-HG is a newly released high-yielding, high-oleic, cultivar with a high level of peanut root-knot nematode resistance. It is a large seeded, medium maturing cultivar with excellent resistance to TSWV. TifNV-HG was released in 2020. Replacement for TifNV-High O/L.
FloRun™ 331 is a new high yielding, medium maturity, high oleic cultivar with resistance to TSWV, White Mold, and Leaf spots.
FloRun™ T61 is a high yield potential and high grading high oleic cultivar. It has outstanding resistance to spotted wilt (TSWV). FloRun T61 was released in 2020. It has a medium seed size with about 650 seeds per pound.
Another question I have talked to growers about numerous times is TSWV tolerance of other varieties. Below is a table from Peanut RX, and it shows “risk” points for spotted wilt, white mold, and leaf spot tolerance of 17 different peanut varieties that can be grown in the Southeast. This information allows growers to assess their risk to tomato spotted wilt, leaf spot diseases and white mold. The lower the number the lower the risk for the production challenge you are looking for. Please refer to Peanut RX to assess other factors such as planting date, and at plant insecticide.
I know that everybody is wondering about what peanut variety to plant this up coming year. Dr. Eric Prostko provided some information about how Georgia O6G is performing over the last few years. The first slide below shows combined UGA OVT data on the performance of Georgia 06G compared to the test average at dryland and irrigated sites since 2015. This data is combined over 8 years and 3 testing locations (Tifton, Plains, and Midville). Georgia 06G yielded higher than the average 7 out of 8 years, according to this data.
The slide below shows yield data for Georgia 06G and Georgia 12Y from UGA OVT that was compiled from 2019 through 2023. The data shows that both varieties show a similar trend in yield over the last 4 years.
Do you have any more variety trial data?
Dr. Scott Monfort, UGA Peanut Agronomist, provided County Peanut Variety trial information a while back. The table below shows variety, number of locations, average yield, grade, % TSWV, and final plant per foot for each variety evaluated this past year. If the variety is highlighted in black, then seed supply is limited. If you have questions, please contact your local county Extension agent.
Over the last couple of years I have conducted three on farm peanut variety trials in Colquitt County. The first irrigated demonstration was planted on May 8th and harvested on October 3, 2023. Plots were 6 rows wide, averaged 500 feet long, and replicated four times.
Another irrigated peanut variety demonstration containing six varieties was planted at the Sunbelt Ag Expo on June 7, 2023. This demonstration was harvested on November 7, 2023. Plots were 6 rows wide, averaged 250 to 500 feet long, and replicated four times.
In 2022, six peanut varieties were planted on May 18, 2022, in this irrigated on-farm demonstration. The peanut varieties included Georgia 06G, Georgia 20VHO, Georgia 18RU, Georgia 16HO, AUNPL-17, and FloRun 331. The six peanut varieties were replicated four times, and the plot length ranged from 400 to 500 feet and 6 rows wide.
Dr. Abney discussed many aspects of insect management in peanuts at the peanut production meeting. The hot topic was TSWV. One way to manage this is through plant insecticide selection. In the last few years, county agents have surveyed growers and consultants with questions pertaining to peanut IPM. One of those questions is: What in-furrow insecticide do growers use for thrips? Information in the slide below indicates an upward trend in Thimet use over the last three years and a downward trend in imidclorid.
Extension agents surveyed peanut fields last year for the incidence of TSWV. The data below shows the %TSWV based off peanut planting date. This data is based off over 300 observations.
Below is an interesting slide showing how at plant insecticide selection can influence severity of % TSWV over the last 4 years.
If you have any questions about peanut agronomy please contact your local county Extension agent.
Have a safe week!!
