Abstract: A new male pistachio variety (Pistacia vera L.) designated as ‘Tejon’ is provided. This variety exhibits earlier flowering dates compared to the industry standard male pistachio variety ‘Randy’, and also produces large quantities of relatively durable and viable pollen.

Abstract: A new male pistachio variety (Pistacia vera L.) designated as ‘Famoso’ is provided that is well-suited for serving as a pollenizer of the female pistachio variety ‘Kerman’ and other mid-to late-season pistachio varieties. ‘Famoso’ has a better overlap in the flowering period of ‘Kerman’ than does the industry-standard male pistachio variety ‘Peters’. ‘Famoso’ is also more precocious than ‘Peters’; ‘Famoso’ produces flowers three to four years after budding as compared to ‘Peters’, which typically takes four to five years to produce flowers after budding. ‘Famoso’ also has a flowering period that is more coincident with the flowering period of ‘Kerman’, while ‘Peters’ often flowers later than ‘Kerman’ and has been reported to have poor blooms in some years.

Abstract: A new female pistachio variety (Pistacia vera L.) designated as ‘Gumdrop’ is provided. This variety exhibits earlier flowering and earlier harvest dates compared to the ‘Golden Hills’ and industry standard ‘Kerman’ cultivars.

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.

Abstract: A new and distinct variety of pistachio tree denominated ‘Lost Hills’ is described. This selections most significant advantage is the superior size and appearance of the in-shell nut. The variety is less chilling sensitive than ‘Kerman’ which improves uniformity of foliation, bloom, nut set, nut fill and uniformity of nut maturity at harvest.

Abstract: A new and distinct variety of pistachio tree denominated ‘Randy’ is described. This cultivar is an early flowering male that will be used as a pollenizer for ‘Golden Hills’ and ‘Lost Hills’. It has excellent flowering synchrony with ‘Golden Hills’ and ‘Lost Hills’ and can be used to cover the earlier part of the ‘Kerman’ flowering period during seasons in which ‘Kerman’ flowering is extended. This generally occurs during seasons of low chill, which are expected to become more frequent in the future due to continued global warming ‘Peters’, the standard male used to pollenize ‘Kerman’, often flowers too late to cover the earlier part of the ‘Kerman’ bloom period under these conditions. ‘Randy’ was selected for high pollen viability, durability, and a high level of pollen production (based on visual evaluation). ‘Randy’ flowers 2 to 4 weeks earlier than ‘Peters’, the standard pollenizer for ‘Kerman’. ‘Peters’ flowers too late to be a very effective pollinator for the new cultivars.

Abstract: A new male pistachio tree (Pistacia vera L.) designated as ‘Tejon’, particularly characterized by very early to early flowering time, is provided. The male pistachio tree ‘Tejon’ is further characterized by a large number of flowers. In addition, ‘Tejon’ is characterized by the production of large quantities of durable pollen with a high germination ratio.

Abstract: A new female pistachio tree (Pistacia vera L.) designated as ‘Gumdrop’, particularly characterized by early flowering time and early harvest date, is provided. The female pistachio tree ‘Gumdrop’ is further characterized by a high yield of nuts which meet commercial standards, maintaining a low percentage of loose shells and kernels.

Abstract: A new male pistachio tree (Pistacia vera L.) designated as ‘Famoso’, particularly characterized by mid- to late-season flowering time, is provided. The male pistachio tree ‘Famoso’ is further characterized by consistent flowering from year to year, and production of a large amount of pollen over an extended period. In addition, ‘Famoso’ is characterized by precocious flowering three to four years after budding.

Abstract: A new male pistachio cultivar (Pistacia vera L.) designated as ‘UC Westside’, to be used advantageously as a pollenizer for commercial female pistachio varieties. ‘UC Westside’ blooms later in the spring than most existing male pistachio cultivars and is particularly characterized by a reduced juvenility period, dense blooms in years with low chill, good pollen viability, and improved bloom synchrony with standard female pistachio varieties, especially ‘Kerman’. It may be used as a replacement for the male cultivar ‘Peters’.
