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.
