In my favorite book on the subject, "Avocado: Botany, Production and Uses" it has several things to say about the Lamb Hass under the section of Achievements - "....is another product of the California avocado breeding programme. It is a 'Hass' - like cultivar which produces 50% more fruits compared to a 'Hass' tree of similar age and growing conditions. It is a precocious bearer, which hold fruits very late in the season even in fierce wind conditions."
There is a section on high density planting of Lamb in this book, like 6' apart in the rows and the photos shown are amazing. Here's Lamb trees that can't be more than 4 - 5' tall just LOADED with gorgeous fruit. I asked Rob Brokaw about the tree size reported to be smaller than Hass. He replied that in his orchards it's not much smaller.
Yep, Carlos is a wonderful sharing person who will revolutionize the Florida industry IMO with his well thought out and presented experiments.
