'VC1-68' (Nut Photo)
Seedling selection from Phoenix, Ariz., made by Virgil Cripe in
1968 and used as a proprietary rootstock by Linwood Nurseries,
Turlock, Calif., for planting in Southwestern U.S. orchards. The
name reflects the number 1 selection made by Virgil Cripe (VC)
in 1968. Nuts are large but relatively thick shelled and with
a very thick middle septum, resulting in low kernel percentage.
Nut: oblong with acute apex and asymmetrical, somewhat acute base;
flattened in cross section; 48 nuts/lb., 48% kernel; kernels golden,
with medium, straight dorsal ridge, relatively deep but open dorsal
grooves; basal cleft usually shallow; ventral surface of kernel
often cupped, with broad ventral groove. Protandrous with early
pollen shed and mid-season pistillate receptivity. Extremely susceptible
(rated 5 on 1-5 scale, 5 = most susceptible) to pecan scab [Fusicladosporium
effusum (Winter) Partridge and Morgan-Jones]. Nuts germinate well
and seedlings are uniform and vigorous, with excellent lateral
root formation.
