Abstract
A new and distinct variety of Pistachio tree denominated ‘Golden Hills’ is described. This selection's most significant advantage over the industry standard is the higher early yield and a greater percentage of this yield is composed of edible split nuts. This variety also has less of a chilling requirement for dormancy resulting in more uniform spring foliation, flowering, pollination and nut maturity at harvest.
