Episode 77: Almond Genetics and Variety Development with Chuck Fleck

4/2/2025

Chuck Fleck joined the Journey to discuss the latest in almond genetics and variety development. Fleck is the director of horticulture research at Sierra Gold Nurseries. During this conversation, he shares his journey into breeding almonds and almond rootstocks, what’s driving his breeding program and what excites him about the future of almond genetics. Fleck also discusses a project with Ohalo using gene editing technology to create a self-fertile nonpareil almond tree.

Nonpareil is the industry standard, but what if other items can come along and create a new industry standard, giving growers more options and not just different versions of the same old options they've got.
