Prunus rootstock, ‘Warootone’

Abstract

A new and distinct variety of Prunus rootstock tree ([ Prunus dulcis x Prunus persica ] x [ Prunus davidiana x Prunus persica ]), which is denominated varietally as ‘Warootone’, which when utilized as a rootstock reduces the growth and height of fruiting cultivars of peach, nectarine, plum, almond, and apricot.

Having thus described and illustrated our new variety of rootstock tree, what we claim is new, and desire to secure by plant Letters Patent is: 
     
       1. A new distinct variety of rootstock tree substantially as illustrated and described, and which is characterized principally as to novelty by producing a tree which can be grafted or budded to peach, nectarine, plum, apricot and almond varieties and which reduces the vigor, by approximately 20% when compared to the same varieties of the same age and cultural practices as the rootstock ‘Nemaguard’ which is the current commercial standard. These observations have been conducted under the conditions prevailing in the San Joaquin Valley of Central California.
