Mary Lu Arpaia and Eric Focht have bred avocado trees in association with the University of California, Riverside, for decades. In the video below, they describe their quest for a better avocado that resulted in the release this year of the Luna UCR™,  a new variety that is the great-grandchild of the Hass. Speaking from experimental UC groves in Irvine, Arpaia and Focht describe the benefits of the Luna and the challenges of creating this new fruit of their labor.
