Description Inventor: Hansen, deceased; Carl J. (late of Citrus Heights, CA); The present cultivar of almond.times.peach hybrid rootstock tree was originated by inventor, Carl J. Hansen, in the aforesaid research and experimental plant nursery and orchards, as a cross--by hand pollination--between "Almond B" and "Peach 1-8-2", and was a selection from a seedling population of said cross; the selection having been made upon the ascertainment--under careful and continuing observation--that the present F.sub.1 clone bore certain desirable characteristics for use as a rootstock. In comparison to Hansen 2168, this cultivar has a greater tendency to produce red coloration of the flowers and of the young leaves and shoots in the Spring, in addition to more red on dormant shoots.
