Interpretive Summary: This chapter describes the success of a self-fertile almond created by USDA-ARS breeders using the National Plant Germplasm System collection.

Technical Abstract: In 1996, Craig Ledbetter of the USDA-ARS Crop Diseases, Pests, and Genetic Research Unit in Parlier, California started breeding almonds with a goal of introducing self-fertility to an historically outcrossing crop. This started with a self-fruitful cultivar called 'Tuono' (DPRU 2301) and led to the eventual development of 'Yorizane', released in 2021. Adoption of this new cultivar will lead to a drastic reduction in the need for pollination services, a potential savings to the industry.
