Narrative

Open-pollinated seedling of eastern black walnut; discovered about 1925 by L. H. MacDaniels, New York State Agr. Exp. Station, Ithaca. Nut: kernel from original tree large, but progeny trees from scionwood are poorly productive and kernels not well developed. Only a few trees now in existence. Bears a large nut with a smooth shell and good cracking quality. Kernel yield and percent are also high. Does not always fill well in northern areas. Evaluation of flowering and fruiting done by W.A. Gustafson and Todd M. Morrissey at the Southeast Research and Extension Center, Lincoln, NE in 1989 with the following results: bud break: April 25; pollen shed: May 17; pistillate receptivity: May 16; maturation date: October 4; number of days from last spring freeze to maturation: 177; accumulated growing degree days above 50 degrees F from the last spring freeze to maturation: 3325; accumulated heat units from the last spring freeze to maturation(base 50 degrees F): 3890. Additional evaluation was done by Todd M. Morrissey and w.A. Gustafson (1989, Same location) during comparison of 40 black wlanut cutlivars/clones for protandry (type IO/protogyny (Type II) and adequated cross pollination with the following results: Pollen shedding=May 14-20; Stigma Receptivity=May 13-21. More information on the preceding evaluation are in the rererences cited int he cituation section below.
