New avocado proves tasty, safer to harvest at UC ANR Research and Extension Centers – Food Blog


A brand-new avocado, one that matches the well-known ‘Hass,’ will strike the world market quickly. The ‘Luna UCR’ range (trademarked and patent pending) has numerous attributes that need to be of interest to both customers and growers, stated Mary Lu Arpaia, University of California Cooperative Extension subtropical cultivation professional based at UC Riverside.

From the grower viewpoint, the tree has to do with half the size of the leading range while producing around the very same yield per tree as ‘Hass,’ indicating that growers might plant more trees per acre, for that reason increasing yield. It likewise makes collecting much easier and much safer.

Another benefit is the blooming habits of the tree. Avocado trees are classified into either Type A or Type B flower types. It is normally accepted that you require both flower enters a planting to make the most of performance. The ‘Hass’ is an “A” flower type and ‘Luna UCR’ is a Type “B.”

This is a prospective increase for growers considering that the existing ranges that are “B” flower types ripen green and normally get lower costs for the grower. Comparable to ‘Hass,’ nevertheless, the ‘Luna UCR’ colors as it ripens.

” Hopefully, it will get comparable go back to the ‘Hass’ once it is a recognized range,” Arpaia included.

Fruit breeding is a long-lasting procedure that she has actually browsed by building on the work of her predecessors. Naturally, Arpaia has actually had strong assistance from coworkers too, consisting of Eric Focht, a UC Riverside personnel scientist and co-inventor of ‘Luna UCR.’

” We had actually been taking a look at ‘Luna UCR’ for a long time and it was constantly a great consuming fruit,” Focht stated. “After the 2003 release of ‘GEM’ (signed up and patented as ‘3-29-5’, 2003) and ‘Harvest’ (patented as ‘N4(-) 5’, 2003) ranges, ‘Luna UCR’ was constantly the leading competitor for a next release due to the little, narrow development routine, “B” flower type and the fruit quality.”

” It’s a really nice-looking fruit too and appeared to be a quite constant bearer from year to year.”

A look at how everything began

In spring 1996, Arpaia took control of the UC Avocado Breeding Program following Guy Witney who led the program from 1992 to 1995, and Bob Bergh whose preliminary efforts in the 1950s were fundamental in the beginning of ‘Luna UCR.’

Arpaia remembers the very first trials in the early 2000s of ‘Luna UCR,’ which were checked together with other appealing choices from the Bergh program. “There were a great deal of ranges that didn’t carry out well, a few of which had bad storage life, an essential characteristic that we require if we are going to get the fruit to customers throughout the nation,” stated Arpaia.

The initial seed and choice were planted at the Bob Lamb Ranch in Camarillo, and initially advanced trials of the ‘Luna UCR’ range were planted in 4 areas: UC Lindcove Research and Extension Center in Tulare County, UC South Coast Research and Extension Center in Orange County, an independently owned farm in San Diego County and another one in Ventura County.

The RECs are amongst the 9 centers run by UC Agriculture and Natural Resources to support research study and inform the general public on local farming and natural deposit difficulties.

ANR Research and Extension Centers end up being essential

Unfortunately, the 2017 Thomas Fire burned the avocado trees in Ventura, stated Arpaia. After a modification in management, the trial situated in San Diego County was likewise ended, leaving the 2 trials at Lindcove and South Coast REC.

” South Coast REC has a long history of supporting research study and extension activities of high worth crops essential to California, consisting of avocados,” stated Darren Haver, director of the South Coast REC, which was typically utilized to reveal growers the brand-new ranges that were being established.

” Many of the REC personnel have actually dealt with the avocado-breeding program scientists for more than twenty years and continue to work carefully with them to make sure the success of brand-new avocado ranges, consisting of ‘Luna UCR’,” he included.

In addition to the assistance offered by South Coast and Lindcove RECs, Arpaia stated that UC Kearney Agricultural Research and Extension Center in Fresno County– another UC ANR center– made it possible for her group to perform crucial postharvest and sensory research study, and customer screening of the fruit, that included approximately six-week trials of fruit rankings for storage life and taste.

” UC ANR has actually played an essential function in our capability to not just determine ‘Luna UCR’, however in preparing it for the world market, too,” she stated.

Preparing to show the world

Since 2015, Focht had actually been gathering information for the patent application. Now that he and Arpaia have actually effectively patented and trademarked ‘Luna UCR,’ they are preparing to broaden production by engaging interested growers with the industrial partner, Green Motion who is based in Spain.

” Green Motion contracted for 1,000 trees to be created by Brokaw Nursery and those trees are presently being dispersed, with earliest field plantings most likely happening in fall,” described Focht.

Focht likewise stated that Mission Produce, based in Oxnard, CA has actually contracted to graft over a little number of “B” flower type pollinizer trees to the brand-new ‘Luna UCR’ range, potentially giving way for a little number of avocados to be offered the list below year.

Once planted, the avocado trees will enter into “complete” production in about 5 years.
