Harris Super originated in Gunnison, Miss. The original tree was discovered in 1958 in a commercial orchard by Edward Harris. It was growing next to the stump of a 'Stuart' tree. This, and the nut's similarity to 'Schley', let to the proposal that 'Harris Super' was a natural cross of 'Stuart' x 'Schley'. Isozyme evidence later indicated this was not the case. The cultivar was introduced in 1960 and was patented by Simpson Nursery Company, Monticello, Fla. in 1961 (Sparks, 1992).
*Note: This is an older cultivar planted in the Young Variety Test at the Tifton Campus. Trees were planted decades ago when care was very different than it is now, and trees received much less care, so production data will reflect this fact. Trees began receiving insecticides in 1962, fungicides in 1970, nitrogen in 1962, and drip irrigation in 1975. The data for this cultivar was collected by several individuals, but the bulk of the data and the comments are from my predecessor Dr. Ray Worley. This information was originally published here: Worley and Mullinix, 1997.
