‘Georgia-22MPR’ is a new high-yielding, high-oleic, TSWV-resistant, root-knot nematode
resistant, and potato leafhopper-resistant, runner-type peanut variety that was released in 2022 by
the Georgia Agricultural Experiment Stations. It was developed by Dr. William D. Branch and Dr.
Timothy B. Brenneman at the University of Georgia, Coastal Plain Experiment Station in Tifton, GA.
Georgia-22MPR has a significantly higher pod yield compared to the Georgia-14N and TifNV-High
O/L varieties in Georgia (Table 1). It also has lower TSWV and total disease incidence than these
other two high-oleic, RKN-resistant runner varieties. Georgia-22MPR also has a higher percentage of
fancy pods (Table 2) and a higher percentage of jumbo seed size (Table 3) compared to Georgia-
14N. Georgia-22MPR combines high yield and dollar values with high TSWV-resistance, RKN-
resistance, and leafhopper-resistance in a medium-large seeded, runner-type peanut variety.
Breeder
Dr. Wayne Hanna
In his turfgrass breeding program at the University of Georgia, Dr. Wayne W. Hanna focuses on developing seed- and pollen-sterile, low-maintenance cultivars with drought and pest tolerance.
He has developed popular forage cultivars such as Tifleaf 2 and Tifleaf 3 pearl millet, Grazer annual rye grass, TifQuik bahia grass, and Mott dwarf elephant grass. He has also developed commercial turfgrass cultivars including Tifton 10, TifSport, TifEagle and TifGrand Bermuda grasses and TifBlair centipedegrass. More recently he has released purplish/red ornamental Pennisetum hybrids (Prince, Princess, Princess Caroline, Princess Molly, Vertigo, First Knight, Tift 11, Tift 15, Tift 26, Tift 40 and Tift 118) and an ornamental perennial peanut, Cowboy.
Dr. Hanna’s research currently focuses on producing seed- and pollen-sterile ornamental grass cultivars (Miscanthus spp., Lovegrass, Rubygrass, Little Blue Stem, Pennisetum alopecuroides, P. hohenackeri, and P. orientale) and on coneless/pollenless pine trees (loblolly and slash) as well as seedless cultivars of cold-tolerant citrus (tangerine, lemon and grapefruit), a variegated Chinaberry tree, and pomegranate.
Dr. Hanna was an Assistant Professor at the University of Florida (Gainesville) from 1970 to 1971. He joined the USDA Agricultural Research Service at Tifton, Ga., in 1971, where he worked cooperatively with the University of Georgia until 2003. Since then, he has been a part-time Professor with the University of Georgia.
He received his B.S. degree in Agricultural Education, M.S. degree in Plant Breeding and Ph.D. degree in Genetics, all at Texas A&M University.
