Interspecific rootstock tree 4-G-816

Abstract

An interspecific (plum-peach) rootstock tree which is medium size, semi-vigorous, upright, medium dense, and well anchored by a semi-fibrous root system; foliated with medium size, elliptic leaves having a serrulate margin, medium length petiole, and medium size, globose, usually alternate glands positioned on base of blade and adjacent portion of the petiole; and flowers from medium size, plump buds; the flowers being large, showy, and pink but staminate, usually lacking or with incomplete pistils resulting in the tree being unfruitful.

I claim: 
     
       1. A new and distinct variety of interspecific (plum-peach) rootstock tree substantially as illustrated and described; the variety being particularly characterized by its ability to reproduce by cuttings planted directly in the field, and--when used as a rootstock for peaches and nectarines--creates dwarfism and, with substantial uniformity, reduces the size of the scion tree to approximately thirty-five percent of the normal height of the same scion tree budded on Nemaguard rootstock; and further characterized by being well anchored, producing few root and trunk suckers, and influences the fruit of the scion tree to attain, in comparison to budding on Nemaguard rootstock, earlier maturity by two to three days, approximately one-eighth larger size, and an increase of one to one-and-one-half percent in soluble solids.
