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’.
