These Avocados Could Be The Answer To Growing The Crop Statewide
Customers love the guacamole served tableside at El Torito in Downtown Fresno so much that about half of them order it. Daniel Avalos is the general manager there.
Avalos and I just ordered some guac. For $10 the appetizer is created on a platter in front of us.
“She cuts the avocados in half and then she’s getting the pulp out of the avocado and putting in the molcajete where we smash the avocado and mix it with veggies,” says Avalos.
Avalos says the restaurant goes through about 500 avocados a week and when they added tableside guacamole to their menu in the 80s it quickly became a hit. Most of the avocados he buys are from out of the country, but he wishes California avocados were available more often.
“California avocados are the best in the world, but we don’t have them all year long,” Avalos says.
One avocado researcher wants to change that. Mary Lu Arpaia is on a mission to find an avocado treethat can withstand the Central Valley’s frosty winters and hot summers. Currently most avocados in the state are grown in Southern California and a narrow strip along the coast.
"I want our avocado varieties to be in season for more than one week. I want it where you can say it's July it's time to pick this variety." - Mary Lu Arpaia
Since 1996 Arpaia’s bred avocado trees across the state for the University of California. On less than five acres at the University of California, Division of Agriculture and Natural Resources Lindcove Research and Extension Center in Lemon Cove, east of Visalia, Arpaia thinks she’s found three varieties that can do just that.
“There’s a void of California fruit on the market in the months of November, December and actually early January,” Arpaia says. “So if we can find different selections that maybe are unique that fit into that window then we help the entire California avocado industry.”
"This is GEM. You can see it's a little more oval or egg shaped than Hass. It has the speckling on the skin."- Eric Focht
Americans ate 2 billion pounds of the green fruit last year and most of those avocados were a variety called Hass. That’s 95 percent of all the avocados Americans consume. Hass is a variety discovered in California in the 1920s. It doesn’t grow well in the valley and the amount that’s grown in the rest of the state is only available at certain times of the year. We just don’t grow enough to compete with the large amount coming in from foreign markets.
The goal is to breed varieties that aren’t super tall, can be planted close to each other and have a high yield. One type Arpaia and her colleague Eric Focht are recommending to growers has all these traits. It’s called GEMand is already sold at nurseries. Arpaia didn't breed it, but they made the decision to recommend that the UC patent and release it.
“This is GEM,” Focht says. “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 will get a yellow kind of golden color to it.”
GEM is actually the great granddaughter of Hass. The second type is nicknamed lunchbox for its small size. The third has no name yet, but Arpaia and Focht think it holds promise.
“Lunchbox, that one peels nice, but I mean this one just falls out of the skin,” Focht says.
Arpaia adds that “it makes wonderful guacamole and I found with a non-replicated test in my refrigerator the fruit doesn’t brown.”
Arpaia says both of these varieties should be on the market within a year or two. That’s good news for California avocado growers who want options.
“I want our avocado varieties to be in season for more than one week,” Arpaia says she'd like certain times of year to be associated with certain varieties of avocados. “I want it where you can say it’s July it’s time to pick this variety.”
"If they could come up with a variety that's similar to the Hass that we could plant down at ground level instead of having it on the hills I'm sure a lot of people would plant them." - Jon Stearns
The avocado industry also has interest in Arpaia’s work in Lemon Cove. Tim Spann, the research program director at the California Avocado Commission, says new varieties producing at different times of the year could widen the California avocado market.
“We have those premium supermarket chains that want California fruit,” says Spann. “So if we can develop other varieties that will expand our season to a year round or nearly year round position that would be fantastic.”
The industry once funded the UC avocado research, but pulled most of their funding a few years ago to focus on pests harming avocado trees. Now he says the commission is thinking of reversing course.
“Within the last six months there’s been a lot of talk about new varieties and how some of those varieties could help us expand our market,” Spann says. “We’re talking internally now about is it time to reinvest in the program.”
Jon Stearns is one of the few avocado farmers in the Central Valley. He grows 25 acres of mainly Hass avocados on a hill outside of Visalia and says the incline of the hill actually helps keep the trees the warm in the winter.
“In the summertime we do some cooling techniques with our emitters and some foggers and stuff like that when it gets really hot, you know over 105 degrees,” Stearns says.
He says he’d love to get his hands on avocado varieties that do well in the valley.
“If they could come up with a variety that’s similar to the Hass that we could plant, you know, down at ground level instead of having it on the hills I’m sure a lot of people would plant them,” Stearns says.
But it’s not just avocado farmers that are interested in the new varieties. The avocado test plot is held at the citrus research center in part to see if avocados grow well in the citrus belt.
Valley citrus growers are looking for alternative crops thanks to a looming threat to their business. The citrus industry is afraid of a disease called Huanglongbing carried by tiny bugs called psyllids. It’s a disease that decimated the citrus industry in Florida and has made its way to Southern California. Bob Blakely with the trade organization California Citrus Mutual says it’s only a matter of time before it reaches the valley.
“I hope it never goes that far,” Blakely says. “I hope that we’re able to come up with resistant citrus varieties before we have to think about going to another crop. I’m just hopeful that the science is able moves quickly enough.”
Still Blakely admits if the disease reaches the Valley citrus growers will eventually need something else to grow. That could be avocados if the findings at the research center near Visalia prove fruitful.
