High quality pecan for the western region of North America. Origin: USDA-ARS (Brownwood, Texas), by T.E. Thompson, L.J. Grauke and L. Lombardini. Cheyenne × Sioux; cross made in 1975; tested as 75-5-6; released cooperatively by USDA-ARS and the Texas Agricultural Experiment Station in 2005. Nut: elliptic with an obtuse apex and an acuminate (pointed) base; laterally compressed in cross section; 53 nuts/lb (up to 38 nuts/lb), with 56% kernel; kernels cream to golden in color; wide, non-trapping dorsal grooves and rounded dorsal ridge; shells out easily into very attractive full halves. Tree: bud growth commences shortly before Desirable in the spring; leaves are characterized by large leaflets, a feature common to other members of this cross family (Nacono and 74-5-60); trees are protandrous, with early to mid-season pollen shed and mid-season pistil receptivity (similar to Caddo and Cheyenne); should be a good pollinizer for, and be well pollinized by Wichita, Choctaw, Hopi, and Kanza; more susceptible to pecan scab than Desirable; moderately susceptible to the yellow aphid complex; medium precocity, similar to Pawnee; comparable in vigor to Desirable and less vigorous than Nacono; form is improved over the willowy, weak growth of Cheyenne; nuts/cluster comparable to Desirable and less than Nacono or Pawnee; time of nut maturity is midseason at College Station, Texas (11-21 Oct.), or about 8 d before Desirable.
