History

The original tree of this variety was grown from a nut planted by Duminie Mire, of Union, St. James Parish, La, in 1836 (Sparks, 1992).

Comments

*Note: This is an older cultivar planted in the Old 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.

The tree is large and vigorous and produces a large, elongated, thick-shelled nut. It has been a fairly consistent bearer of good quality kernels, but the thick shell causes low percent kernel. The nut is attractive for an in-shell nut and kernels are high in oil. Shellers would not like the low percent kernel but would like the high quality kernels. One of my favorites of the older varieties. Not recommended.
