(Nut
photo) Orig. as chance
seedling in Gunnison, MS discovered in 1952 by Edward Harris.
Introd. in 1960. Plant patent 2051, issued Apr 25, 1961, assigned
to Simpson Nursery Co., Monticello. FL. Parentage unknown; once
thought to be 'Stuart' X 'Schley', but that parentage is inconsistent
with isozyme patterns ('Schley' and 'Stuart' are aa for phosphoglucose
isomerase, while 'Harris Super' is ab). Nut: oblong with long
acute apex and obtuse base; round in cross section; shell heavily
specked, prominently ridged; 50 nuts/lb, 53% kernel; kernels with
wide dorsal grooves, deep secondary dorsal grooves, wrinkled texture.
Protogynous. Precocious and prolific. Some scab resistance in
GA, but very susceptible in FL. Not recommended for planting in
any state.
