The fruits of climate change

Zaiger pluot whole and sliced.

The other day I found myself looking through the plant patents held by the Zaiger’s Genetics team. The Zaigers, a family of plant breeders led by a UC Davis Plant Pathology graduate, have developed some very cool fruits. You may know of the pluot, and apparently they have a peach with low acid that has taken the world by storm. They have developed many plants with important and beneficial characteristics besides taste – but they taste great too.
I know some people dislike patents, but I have no objection to people who have developed these novel plants having patents on them. But considering what it takes to breed wonderful fruit tree varieties like these, you can understand why these patents exist.
Zaiger’s Genetics has been breeding fruit trees for decades, with many interesting successes. For some background on Floyd Zaiger a fruit innovator to the world and his family that continues this work, there was a great article in SFGate last year. One fruit they describe in that article is a hybridized nectarine popular in Spain:

One of Zaiger’s hybridized nectarines grown in Spain can mature 10 days ahead of anything else in Europe – “so they have a market almost all to themselves,” he says. That 10-day difference can make or break a country’s fruit industry.

Lately, some people have been objecting to the use of hybrid crops, but I don’t have a problem with it. Early maturing fruit can have financial benefits as we see here – but in a time of climate change, shifting the maturity rates could be a really important strategy.
The Zaiger Genetics team has developed a huge number of useful fruits. One article some years back on Designer Fruit described some others:

Among his achievements, Zaiger, 78, has found a way to reduce the acid level in peaches, give unripe apricots an appealing red blush, and make white nectarines—previously a mushy mess—firm enough to be shipped around the world.

Firmness for shipping may not be your favorite characteristic, but if farmers can’t get fruits to customers that is a problem. And the fewer fruits lost in transit, the better. Reducing food waste is something worthwhile.
So shifting maturation – to either earlier or later, as the Zaigers have accomplished – is valuable. Texture and shipping characteristics also benefit farmers and consumers. There’s a list of other types of features on the Dave Wilson Nursery (the Zaiger’s distributor) that are under investigation. Cool stuff.
But the particular piece that struck me last week was one specifically about one of the recent patents that was issued. It’s on a cherry called Royal Tioga, selected for fruit that ripens early and is large. It seems to me this could be a great idea not only to extend the range of this tree – but considering these times of climate change it might be beneficial to bloom and fruit earlier to potentially avoid temperatures that are too high or conditions that are too dry. There may be other plants that could require other shifts for other locations, or maybe survive wetter situations.
In a post at Txchnologist, Michael Keller reported on this new patent, and talked to the Zaiger team. Txchnical Improvements: Onward, Cherry Development! The work that went into this was described by Floyd’s daughter Leith:

“It took 45 years of sorting through the junk offspring to find the seedlings that took us where we wanted to go,” says Gardner. “Ninety-nine percent of them didn’t have the qualities we were looking for.”

The Zaiger team uses only conventional breeding strategies. That’s completely fine – I would never withhold techniques or strategies from folks who want to use them. Although once they did experiment with something else:

He once zapped some of his plants with an X-ray machine to see if he could cause their mutation. Another time he stormed into his greenhouse with a hammer and pounded some of his buds—hoping to shock them into spontaneous change. (Neither experiment worked.)

Ok, so percussive genetics didn’t pan out. That said, I have seen a plant made with ultrasound, so it’s not entirely unlikely to work…
But focus on the time and the rate for this one cherry: conventional breeding by the top specialists in this field took 45 years, with a 99% failure rate. The Designer Fruit article also notes:

It’s not unusual for him to wait more than 15 years to make money from a new variety. After nearly three decades of working on the peacotum, Zaiger hasn’t seen any revenue from it. “It’s not get-rich-quick,” he says.
Because of those economics, his company spent about 30 years in the red, though it is now profitable.

Don’t get me wrong – I think the Zaiger’s Genetics work is heroic. But I wonder if we have that kind of time in a changing climate, and if other breeders who might want to work on this can persist in the kind of economy we have today. And I wonder if people who want to withhold certain plant technologies – some that might speed up our abilities to shift fruiting or adapt to changed conditions – from plant scientists really understand that. Finally, shouldn’t someone like the Zaigers who spend many long decades to develop a new and useful fruit be able to patent what they have done so they can stay in business?

  1. Good article and points well made
    The question of how the Zaiger’s of the world should be rewarded is a vital part of the Intellectual property discussion across the whole Idea economy of the world.
    In Australia we growers must pay 5% of the sale price of our fruit as a royalty to the Zaiger’s local company, in addition to an initial payment for the royalty for the bud . This could be 50 to 100% of the margin for the grower.
    Despite this, the growers are still planting Zaiger varieties. 75% of my peaches are Zaiger, great taste and good appearance.

    1. Interesting–I didn’t know about the local company piece. Thanks for that detail. And I’m glad to hear you have success with the peaches.
      And yeah, there is a larger IP discussion. And I think people ought to consider carefully if they want (or don’t want) protection for a local plant breeder in the developing world to have rights as well.
      Another point I didn’t make was about grant cycles. 45 years + 99% fail = not gonna happen in the grant world for a single lab. There may be more ongoing support for some programs, but that’s a pretty risky bet in the current economic climate and the known proclivities of Congressional “science” committee folks at least in the US.

  2. There are many reasons to void or revoke all lifeform patents and intellectual
    property claims.
    Patents are used to convert what was common practice like sharing seeds into
    a crime. Now even farmers need to have a a lawyer on retainer to avoid
    being sued by patent trolls. Careful while you step through the minefield
    of patent restrictions and litigation.

  3. The vast majority of humans work hard their whole lives.
    It is only those with a depraved sense of entitlement who think
    the rest of us owe them something.
    Intellectual property lawyers, politicians bought and paid for by
    corporations and their media propagandists have been trying
    to convince the rest of us that it is criminal to share seeds or
    food or ideas.

    1. So if some farmer or breeder in the developing world had created and cultivated a great plant with cancer-killing properties, you’d want any pharmaceutical company to be able to swoop in without any benefit to that farmer?

  4. I can not see a Corporation or lawyer in the story, just a single family with a genetic defect that causes them to breed new varieties and tastes.
    They hold no single gene patents, do not bank genes, do not use gene modification and allow growers to access the varieties.
    How could the Zaiger family continue to produce these innovations in taste and productivity without patents and royalties?
    As family orchardist I can assist this needy family by using their product and paying their price, in the hope that my grandson can continue to source varieties from Zaigers in 50 years time.
