Abstract

A new and distinct rootstock variety of avocado tree characterized by its high yield resistance to Phytophthora root rot caused by Phytophthora cinnamomi. This variety has a high level of resistance comparable to the 'Duke 7' rootstock variety. It is also characterized under some field conditions by producing a somewhat smaller tree, when grafted with a 'Haas' scion, than that typical of a 'Duke 7' rootstock.
