Abstract

This invention relates to a new and distinct variety of pistachio tree primarily identified by its rounded upright growth habit, pleasing green color of mature foliage and its production of female flowers and seed.

The following is claimed: 
     
       1. A new and distinct variety of pistachio tree, identified as PN-17-F, characterized by a mature tree of rounded upright shape, having several main branches and usually a central leader; rapid growth, abundant, leathery foliage, ease of propagation by budding or grafting; and further characterized by the abundant production of female flowers, in clusters, followed by seeds which are especially desirable for planting when pollenized by the male variety, identified as PN-46-M, said hybrid seeds producing a fast growing, disease resistant tree of value for use as understock upon which to bud or graft commercial nut bearing varieties of pistachio such as `Kerman`.
