Walnut Patents (Class PLT/154)
  • Publication number: 20200120841
    Abstract: A new and distinct Juglans cultivar named ‘Cliff Clone’ is disclosed, characterized by an increased propensity to thrive in sandy soils which have been replanted into walnut. Trees grown on the new rootstock variety have shown significantly better vigor as well as increased walnut production when planted in the presence of the pathogen Pratylenchus vulnus and in soil known to have walnut replant disorder. The new variety is a Juglans hindsii x regia, for use as a commercial rootstock for grafting or budding onto.

    Abstract: A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by extremely rapid growth rate, very strong central stem tendency, and excellent straightness, thereby producing excellent timber qualities. The new variety has good nut bearing qualities. Nut crops are abundant and annual. Nut bearing begins early in the life of the tree. This new variety of black walnut tree (Juglans nigra L.) was discovered by the applicant near South Raub, Tippecanoe County, Ind. in a black walnut planting of seedling progeny from previously selected trees for outstanding timber producing potential. This selection has been designated as BW500, a seedling progeny of BW 249 in records maintained by the applicant on the performance of the selection and grafts made from the selection and will be known henceforth as ‘Beineke 4.

  • Patent number: PP12898
    Abstract: A cold-resistant Persian walnut cultivar originating as an open pollinated seedling from a population of seedlings, for which the identity of the female parent was not recorded, that were planted at the Iowa State University Horticulture Research Farm, Ames, Iowa, USA in 1971, and evaluated as ISU71-EI8. Past literature and growth characteristics suggest that one of the parents was probably ‘Hansen’ (unpatented) Persian walnut. The other parent may have been ‘Colby’ (unpatented) Persian walnut. Tree has consistently exhibited minimal shoot die-back when exposed to late-fall/early-winter, mid-winter, and late-winter freezes; when exposed to minus 35.6 degrees Celsius, trees suffered only minor to moderate shoot die-back while other cultivars and selections were killed or severely injured. Catkin survival has been recorded following expose to minus 32 degrees Celsius.
