Kerman

Kerman is the industry standard female pistachio cultivar grown in California. Long hot summers required to ripen. Bears significant crop in the 6th leaf. Tends to alternate bear. Moderate vigor. High chilling requirement – 800 hours. Late nut maturity – September to mid-October. Pollenized by Peters.

​

Golden Hills (USPP# 17158P3)

Golden Hills is a relatively new and popular female pistachio cultivar released by the University of California in 2005 which produces a greater yield and higher percentage of split edible nuts than Kerman and maintains a low percentage of loose shells and kernels. The most important characteristic about Golden Hills is the early harvesting date – which is two to four weeks earlier than the industry standard Kerman.

Lost Hills (USPP#17701P3)

Lost Hills is a relatively new female pistachio cultivar released by the University of California in 2005 which produces a higher percentage of split edible nuts than Kerman, with nut sizes larger than Kerman. The most important characteristic about the Lost Hills variety is the earlier harvested date which is about two to four weeks earlier than the industry standard Kerman.

​

Gum Drop (USPP#28953P3)

Gumdrop is a very new female pistachio cultivar released by the University of California in 2016.  It produces a comparable nut yield to Golden Hills and Kerman and the nuts have a high inshell split nut percentage. The most important characteristic of the Gumdrop variety is the extra-early harvest timing about ten days earlier than both the Golden Hills and Lost Hills varieties.

Pollenizer Varieties:

​

Peters

Peters is a male pistachio, pollenizer for Kerman. Does not bear fruit. One Peters pollenizes up to eleven females. Chilling requirement 800 hours.

 

Randy (USPP#18262P3)

Randy is an early flowering male pistachio that is a good pollinizer for both Golden Hills and Lost Hills varieties. It has flowering synchrony with Golden Hills and Lost Hills and may be used to cover the earlier part of the Kerman flowering period. Randy has a high pollen viability, durability and high level of production.

Famoso (USPP#28994P3)
Famoso is a male pistachio, that produces good quantities of viable pollen produces flowers at a younger tree age than Peters and more closely matches the flowering dates of Kerman than does Peters especially in seasons where Kerman has an extended bloom.

Tejon (USPP#28931P3)

Tejon is an early flowering male pistachio which can be used as the principal pollinizer for Gumdrop, due to its flowering synchrony with Gumdrop and the good quantities of viable pollen produced. Tejon may be planted as an early-flowering male in orchards of Golden Hills and Lost Hills to improve pollination in years with low chill.
