'Steuck'(Nut photo) ('Hirschi') Native seedling discovered in 1922 by J. F. Tiedke on bottom land of the Osage River near Papinsville, Bates County, MO, on land owned by G. H. Steuck. Introduced in 1929. Popularized in 1940 by A. G. Hirschi of Oklahoma City, OK as 'Hirschi' and propagated in 1954 by Inter-State Nursery, Hamburg, IA under that name. The name 'Hirschi' is much more widely known than 'Steuck'. Nut: oblong, with acute apex and base; round in cross section; shells with prominent dark stripes; 72 nuts/lb, 49% kernel; kernels golden to light brown in color, with deep, narrow dorsal grooves; tight ventral groove and basal cleft. Protandrous , with mid-season pollen shed and mid- to late-season pistillate receptivity. Initially considered scab resistant, but now quite susceptible. Recommended (1990) (as 'Hirschi') for planting in KS, MO and OK.
