'Nacono' (Nut Photo) Originated
from a controlled cross ('Cheyenne' X 'Sioux') made in Brownwood, TX by E. J. Brown
and G. D. Madden in 1974. Tested as 74-5-55 by T. E. Thompson,
L. J. Grauke and J. B. Storey and released in 2000. Nut: oblong
with acute apex, and an acuminate (pointed) base; round in cros
section; 44 nuts/lb, 56% kernel; kernels cream to golden in color,
with shallow dorsal grooves and rounded dorsal ridge. Nuts shell
out easily into full halves and have excellent eye appeal. Protogynous,
with late season pollen shed and early to mid season receptivity.
Resistant to scab [7 year mean nut scab of 1.06 (where 1=resistant,
5=very susceptible) while 'Desirable' tested at 1.90 and 'Stuart'
at 1.21]. Moderately susceptible to yellow and black aphids. Trees
are vigorous, with branched central leader form (photo of tree form) with strong limb angles. Bud growth
commences shortly after 'Desirable' in the spring. Leaves are
characterized by large leaflets, a feature common to other members
of this cross family (74-5-60 and 75-5-6). Medium precocity (comparable
to 'Pawnee'). Nuts average 3 per cluster. Shucks are glossy yellow
green (photo of
nuts in shucks), with
medium suture wings near the apex. Nuts mature mid-late October,
about one week prior to 'Desirable'. 'Nacono' bears well, but
avoids overbearing.
