History

'Chickasaw' was developed from a cross between 'Brooks' and 'Evers'. The cross was made in 1944 by L.D. Romberg at the U.S. Pecan Field Station, Brownwood, TX. The resulting selection was distributed as scion wood beginning in 1957. 'Chickasaw' was released by G.D. Madden in 1972 (Sparks, 1992).

Comments

*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.

We only tested a single tree of this cultivar, and that was too many. Alternates between an overload of poor-quality nuts and low or no yield the next year. Sometimes it overloads so badly that whole limbs are killed from the stress. Not recommended.
