What is in this article?:
• Many differences exist among the varieties and, therefore, it is important to assess what characteristics are most important for their production area.
• Growers should choose several varieties to plant to reduce risk and improve their chances of success every season.
Oglethorpe has above average yield in both north and south Georgia. It has good resistance to leaf and stripe rust but only fair tolerance to powdery mildew. This variety has Biotype L Hessian fly resistance. Care should be taken with nitrogen applications as it only has fair straw strength.
Baldwin is a UGA release that has good Hessian fly resistance, good leaf and stripe rust resistance, good yield, test weight and soil borne virus resistance. It is moderately resistant to powdery mildew. It is medium late in maturity with a moderate vernalization requirement.
Southern States Seeds:
Southern States (SS) 8641 is a good yielding wheat with excellent disease and Hessian fly resistance. It has good straw strength and test weight. It matures later than AGS 2000 and Pioneer 26R61 and should not be planted past the recommended planting window in Georgia.
SS 8308 has a very long vernalization requirement and is recommended for north Georgia only. Its pest resistance is fair to poor but performs well in north Georgia. Fungicides and at plant insecticides are recommended for use when planting this variety.
Fleming is the earliest maturing wheat in Georgia. It has very little vernalization requirement and, therefore, should be planted in the later 1⁄4 portion of the recommended planting period. In late plantings in Georgia (after recommended planting periods), Fleming provides some of the highest yields of all the varieties tested. Caution: Fleming has a physiological spotting that is easily mistaken for leaf disease. All lesions should be carefully examined to make sure a proper diagnosis is made when considering a fungicide.
Jamestown is a new variety with good yield but moderate susceptible to leaf rust, good resistance to powdery mildew and stripe rust. It is susceptible to Hessian fly. It is recommended that this variety be treated with an at-plant insecticide.
Roberts is one of the oldest public varieties still recommended however it is recommended for forage production only. It has good resistance to glume blotch but is susceptible to all other foliar diseases and requires a fungicide for adequate seed production. It is a late maturing variety that has a long vernalization requirement.
AGS 2000 is considered one of two standard wheat varieties grown in Georgia. The other is Pioneer 26R61. AGS 2000 requires the use of a fungicide to maximize yields. Although this variety is resistant to Hessian fly, AGS 2000 may respond to an insecticide since several new races of Hessian fly are prevalent.
AGS 2020 is approximately four days earlier than AGS 2000 and has good disease resistance, fair yield, test weight and straw strength. It also has very good soil borne mosaic virus resistance. AGS 2020 has only fair tolerance to Hessian fly and therefore should be treated with an at-plant insecticide.
USG 3209 has been sold in Georgia for several years. It demonstrates some susceptibility to certain biotypes of Hessian fly and therefore should be treated with an at-plant insecticide. It is an early maturing variety and well suited for the upper coastal plains. This variety responds well to a fungicide. It has very good yield if managed with pesticides.
Please be aware of all rules and regulations regarding certified seed and patented or PVP varieties.
Consider using varieties tagged with an official certification tag. Certified seed ensures the highest quality seed available with good germination and freedom from noxious weeds. Contact the Georgia Crop Improvement Association regarding any questions with certified seed at 706/542-2351
