Issues in Pomegranate Breeding
Pomegranates were actually first
introduced in California by the Spanish missionaries in the mid-1700s. (“Pomegranate”).
“Over the past ten years, pomegranate production has increased by more than
five times” (“Pomegranate”) as it gained popularity among the public. It is high
in nutritional values such as antioxidants and vitamin C and they can “thrive
where other fruits cannot” through drought and salt. (Fulton).
With so many benefits, it is surprising
that pomegranates are not the most sold fruit in the United States, as observed
by John Chater, “a post-doctorate scholar studying pomegranate cultivars at the
University of California, Riverside.” (Fulton). Along with his colleagues, John
Chater hopes to change the market for pomegranates by introducing a wider range
of varieties in color and flavor of pomegranates. As of now, he is studying the
tastes of the public and is growing edible pomegranates, including “Parfianka…[and]
Golden Globes”. (Fulton).
As far as pomegranates go, I personally
love consuming them. They have a unique flavor and are rich in nutrients. But when
I am in the grocery store in front of the pomegranate crate, I hesitate about whether
to buy them or not because they are a process to eat. With so many individual
pieces about the size of a pea and the seed alone accounts for about half of
the whole size, eating them becomes a long and dreary process. Thus, John
Chater is plausible for the idea of making pomegranates more mainstream;
however, breeding it is not a wise choice because it causes the rise of many
issues similar to the agricultural crops today and controversies about the
ethical and moral concerns of changing pomegranates.
First, many agricultural crops have been domesticated,
of which modern corn is the most thoroughly domesticated crop. “Over
generations, humans have made…changes in corn’s genetic structure, altering the
plant’s shape and taste… [As a result, it became] completely dependent on
humans for its existence [which means] were it not planted, tended, and stored
by people, it would become extinct in several years’ time.” (Meyer). Second,
they are a monocultural crop which can cause serious damages. Corn plants now
are produced in massive numbers around the United States, all with similar
genetic compositions. If, in the future, a deadly disease develops that the present
corn variety are not resistant to, the massive monoculture of corn will all be
destroyed since they have similar genes without genetic diversity. Likewise,
this could happen to pomegranates as well. If they become popular enough to
produce in massive numbers and then is domesticated, there is a high risk that one
single disease can wipe out the pomegranates; they have no diversity therefore
no possibility that at least one of the pomegranate variety contains a resistant
gene of some sort. As a result, pomegranates may no longer exist in the future.
This would not be a problem if pomegranates are bred naturally. Natural
hybridization promotes genetic diversity whereas artificial hybridization only
narrows the genetic traits to what humans desire such as increase nutrition,
tolerance to disease and environmental impacts. So instead of artificial
hybridization, biologists and agriculturists studying pomegranates should leave
the pomegranates up to nature and allow them to breed together themselves.
On the other hand, the issue of cultures
and beliefs of pomegranates still exists. There is always the possibility that
among the hundreds of cultures and native tribes, pomegranates may be one of
their spiritual plants and they may find breeding them as an intrusion to their
way of life, causing tension between the researchers and the natives. So the
best way to solve all of these problems is to leave the pomegranates as they
are now.
Pomegranates are a great fruit to
consume occasionally. The dangers of John Chater’s way of making pomegranates
mainstream is too high; they should then be left alone.
This was a really unique and interesting response. I don't know a lot about pomegranates and their domestication. Based on your response I'd agree with you in that pomegranates should just be left alone.
ReplyDeleteI really like your response to this news article. I never would have thought or known about all these facts about pomegranates. I do not very much enjoy the taste of pomegranates like you seem to describe but I agree with the other benefits of eating them.
ReplyDeleteThis was really a well organized and well developed response. I loved the part where you said " eating them becomes a long and dreary process", because it is really funny. Your evidence was really well incorporated to support your perspective. I agree with your perspective; I think it is more important to preserve pomegranates than take the risk to extinguish them all.
ReplyDeleteThe most tangible explanation to breeding crops was the corn example; it did a great job showing what can be possible for any other crop grown by man. I personally love pomagranates as well, but I wish they were at least a little more available in supermarkets. Perhaps there is a way to slightly increase the crop yeild without making the pomagranties completely reliant on human attendance.
