A group of trained and dedicated volunteers have been tasting avocado samples at the UC Kearney Agricultural Research and Extension Center in Parlier to determine whether the GEM avocado variety can stand up to the tried-and-true Hass in grocery stores, reported Dale Yurong on ABC 30 Action News.
Yurong visited the sensory lab at Kearney where nine tasters have been meeting for months to help inform UC and USDA research that may enable commercial production of avocados in the San Joaquin Valley, an area believed to be unsuitable because of hot summers and cold winters.
The panellists identify avocado characteristics like nutty, stringy and buttery. "You're getting into the texture, you're getting into a lot of different nuances of flavor," said taster Shannon Aguilar.
GEM avocados grow on smaller trees than Hass and GEM has a tear-drop shape, while Hass is more pear-shaped. But the real test will be comparable flavor and tolerance to valley conditions.
"We believe it has a little more heat tolerance and a little more cold tolerance," said UC Cooperative Extension specialist Mary Lu Arpaia.
The GEM may give local farmers a new crop option. One has already planted two acres of GEM.
"It's something that we probably need in this area. Something we can do and we wouldn't have to import it from other parts of the country or the world," said Marvin Flores, environmental health and safety specialist at Kearney and a member of the avocado taste panel.
California avocados are the best in the world. So says downtown restaurant manager Daniel Avalos in a Valley Public Radio story by reporter Ezra David Romero.
The fact that they currently thrive only on a small swath of coastal Southern California is being challenged by UC Cooperative Extension specialist Mary Lu Arpaia. She is on a mission to find avocado varieties that withstand the hot summers and cold winters of the San Joaquin Valley, where irrigation water and crop land are more abundant and cheaper.
She hopes to find avocado varieties that ripen at various times of year, and varieties that might be an alternative crop for citrus growers should huanglongbing, a disease that has devastated the Florida citrus crop, take hold in Central California.
"There's a void of California fruit on the market in the months of November, December and actually early January," Arpaia said. "So if we can find different selections that maybe are unique that fit into that window, then we help the entire California avocado industry."
Romero visited the UC Lindcove Research and Extension Center to see the trees in Arpaia's study. Currently, the vast majority of California avocados are the Hass variety. The goal is to breed varieties with similar eating quality that grow to a moderate height and have high yield. One potential that is already being produced by nurseries is called "gem."
"This is gem," said Eric Focht, a staff research associate in Arpaia's lab. "You can see it's a little more oval or egg shaped than Hass. It has the speckling on the skin. Now as this ripens, it will turn dark and a lot of times the speckled lenticels with get a yellow kind of golden color it it."
Another promising variety is called "lunchbox" because of its small size. According to Focht, it "just falls out of the skin." Arpaia said, "It makes wonderful guacamole and I found, with a non-replicated test in my refrigerator, the fruit doesn't brown."
Arpaia's favorite guacamole recipe is featured at the end of the story on the KVPR website.
Gary Bender, an advisor with UC ANR Cooperative Extension in San Diego County, believes that increasing per-acre yield will help farmers stay in business.
“We've been growing avocados wrong all these years and we're finally starting to figure it out," Bender said.
He planted trees 10 feet apart in a research trial, instead of the standard 20 feet spacing. Instead of letting the trees grow tall, the standard practice, he pruned them regularly to keep the trees short and fat.
The study was a huge success, yielding nearly 13,000 pounds of Haas avocados per acre, McClurg reported. Usually farms in the area yield between 6,000 to 7,000 pounds per acre.
