Registration of 'Georgia-03L' peanut.

'Georgia-03L' (Reg. no. CV-79, PI 634333) is a new large-podded runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar that was released by the Georgia Agricultural Experiment Stations in 2003. It was developed at the University of Georgia, Coastal Plain Experiment Station, Tifton, GA.

Georgia-03L originated from a cross made in 1991 between 'Georgia Browne' (Branch, 1994) and 'VA-C 92R' (Mozingo et al., 1994). Pedigree selection was practiced within the [F.sub.2], [F.sub.3], and [F.sub.4] segregating populations, and performance testing began in the [F.sub.4:6] generation with the advanced pure breeding line GA 962533.

Georgia-03L has a high level of resistance to spotted wilt disease caused by Tomato spotted wilt virus (TSWV) comparable to 'Georgia Green' (Branch, 1996). Georgia-03L is unique from other runner-type peanut cultivars in having a distinctively higher percentage of fancy pods (riding a 1.35-cm spacing set on pod presizer). It has pod size similar to Virginia-types (>40% fancy pods), however it has seed weight similar to runner-types (65-70 g [100.sup.-1]). Georgia-03L combines TSWV-resistance with large smooth pods and excellent yielding ability.

In 15 tests conducted at multiple locations in Georgia from 1998 to 2002, Georgia-03L was found to be significantly higher in yield than Georgia Green with the same high dollar value return per hectare. Georgia-03L also produced about twice the percentage (37 vs. 19%) of jumbo runner seed (riding a 8.33 by 19.05 mm slotted screen) as compared to Georgia Green, but had fewer medium and No. 1 seed.

Georgia-03L has similar maturity, pink testa color, protein content, oil content, O/L ratio, and roasted flavor as Georgia Green and 'Florunner' (Norden et al., 1969). Georgia-03L also has very good stability and a wide range of adaptability throughout the U.S. peanut production areas (Branch et al., 2001, 2002, 2003).

U.S. Plant Variety Protection is pending for Georgia-03L. Breeder seed of Georgia-03L will be maintained by the University of Georgia, Coastal Plain Experiment Station at Tifton. Foundation seed stock will be available from the Georgia Seed Development Commission, 2420 S. Milledge Avenue, Athens, GA 30605.
