Variety of Prunus rootstock named ‘A B 207’

Abstract

Disclosed is a new and distinct variety of prunus rootstock useful for peach, plum, nectarine, apricot, cherry and potentially other scionic and stone fruit varieties; and particularly useful for plum varieties such as ‘Crimson Glow’ and/or ‘Black Splendor’ and/or ‘Jo Anna Reds’. The present variety appears has considerable tolerance to infection by Armillaria (aka Oak Root Rot) which is a common root fungi, infecting many soils in California, particularly where oak trees have been grown.

Having thus described and illustrated the new variety of rootstock, what is claimed as new and desired to be secured by plant Letters Patent is: 
     
       1. A new and distinct variety of rootstock substantially as illustrated and described herein for use primarily with plum, peach or nectarine scions, which is characterized principally by its resistance to  Armillaria  root fungus, its absence of vestigial wings on leaf petioles, and its inducement of larger fruit.
