Abstract
An improved Prunus dulcis variety is provided that is well suited for serving as a pollenizer for the widely-grown "Nonpareil' variety (non-patented in the United States). Good bloom overlap in combination with good production quality is displayed. The tree exhibits an upright and spreading growth habit. Abundant lateral vegetative growth is produced on current season shoots which makes possible high tree productivity. Desirable fruit and kernel characteristics for shelled and possessed almond production are displayed.
