Cultivation

Early-blooming, Nonpareil-type almond used as a pollinizer for the early Nonpareil bloom. Origin: USPP 8236 in 1993 by William Spoto, Yuba City, Calif., from an almond chance seedling found in an almond seedling rootstock orchard of Nonpareil and Drake that had been planted in the early 1900s. Bloom: 3 days before Nonpareil. Nut: medium to large size with moderate shell seal and harvest just after Nonpareil. The suture of the shell has a wing more prominent than that of Nonpareil. Kernel: Nonpareil type but larger. About 27 mm in length, 14 mm in width, and 9 mm thick and 1.3 gkernel. About 51% kernel to nut by weight. Tree: upright in structure. Leaf glands globose, averaging 2 per leaf, mostly alternately positioned on petiole and base of blade. Crop borne usually on spurs though with considerable production on shoots, often on smaller fruiting wood. Fruit:
