‘Georgia-18RU’ A New High-Yielding, Normal-Oleic, TSWV-Resistant, Leaf Scorch-Resistant, Medium-Large Seeded, Runner-Type Peanut Cultivar

Summary

Georgia-18RU is a new high-yielding, normal-oleic, tomato spotted wilt virus (TSWV) resistant, leaf scorch resistant, medium-large seeded, runner-type peanut variety. It is intended for the same market as other normal-oleic runner-types.

Situation

Georgia leads the nation in total annual peanut production with nearly half, and average state peanut yields have more than tripled in the latter half of the 20th Century. Publicly developed cultivars have played a major role in this overall process, and the quality of this vitally important commodity has likewise been enhanced.

Response

The Georgia Peanut Breeding Program is actively involved in the development of improved cultivars with desirable traits for increasing dollar value, yield, grade, disease resistance, insect resistance, virus resistance, nematode resistance, aflatoxin resistance, drought resistance, better shelling characteristics, longer shelf-life, and enhanced flavor and nutritional qualities. Possibly, no other single research effort can benefit the whole peanut industry as much as an improved cultivar.

Impact

‘GEORGIA 18RU’ is a new high-yielding, normal-oleic, TSWV-resistant, leaf scorch-resistant, medium-large seeded, runner-type peanut variety that was released by the Georgia Agricultural Experiment Station in 2018. It was developed at the University of Georgia, Coastal Plain Experiment Station, Tifton, GA. During five-years averaged over 34 multilocation tests in Georgia, Georgia-18RU had similar TSWV and total disease incidence, yield, and dollar value return per acre compared to Georgia-06G. However, Georgia-18RU had significantly higher percent TSMK grade and greater number of seed per pound compared to Georgia-06G. Georgia 18RU was also found to have a very high level of leaf scorch resistance compared to other runner varieties. Georgia 18RU combines high-yield, high-grade, high-dollar value, TSWV-resistance, leaf scorch-resistance with the normal-oleic trait to meet major peanut butter demand, potentially less post-harvest aflatoxin production (normal-oleic vs. high-oleic), and maintaining greater genetic diversity among U.S. peanut varieties.
