The navel orange has existed for over 150 years. Every single one of them — every navel orange grown anywhere on earth since the 1870s — descends from a single mutant tree that appeared in a monastery in Bahia, Brazil. The tree could not reproduce. Its fruit contained no seeds. A cutting was sent to the United States Department of Agriculture, which distributed it to growers in California, who grafted it and grew it and grafted it again. The process continues today.
Every navel orange you have ever eaten was a clone. A genetic copy of a genetic copy, stretching back 150 years to one tree that nature would have allowed to die without offspring.
We call this convenience. And it is convenient. But it is worth pausing to ask what we have built — and who now controls it.
What Seedless Actually Means
Seedless fruits are not a modern invention. Bananas have been cultivated without seeds for thousands of years. Seedless grapes appear in ancient records. But the biological reality behind all of them is the same, and it is something most people have never been told directly.
A seedless fruit is a fruit that cannot reproduce.
That is not a metaphor or an oversimplification. It is the biology. Fruits exist, evolutionarily, as vessels for seeds. The plant produces the fruit to attract animals that will eat it, carry the seeds, and deposit them elsewhere. The seed is the point. The fruit is the packaging.
A seedless fruit has no seeds to deposit. It cannot start a new plant. It is, in the language of plant biology, sterile.
Seedless fruits are produced through two main mechanisms. The first is parthenocarpy — the fruit develops without fertilisation of the ovule at all. The second is stenospermocarpy — pollination occurs, fruit development begins, but the embryo aborts before a mature seed forms. In the case of triploid plants like seedless watermelons, the plant is given three sets of chromosomes instead of the usual two, which disrupts the meiosis process and prevents viable seed formation. The resulting plant can grow fruit but cannot reproduce through that fruit.
Michigan State University describes it plainly: seedlessness to the plant is useless, since it fails to produce offspring. That is why most seedless plants are propagated through grafting or cuttings. A human hand must intervene every generation, or the variety disappears.
The convenience is real. So is the dependency it creates.
The Banana Problem
The Cavendish banana — the one sold in every supermarket in the world — is the most consumed fruit on earth. It is also one of the most precarious monocultures in the history of food.
Every Cavendish banana is genetically identical. They are all propagated from offshoots, not from seeds. This means the entire global supply of a fruit consumed by billions of people shares the same immune system. The same vulnerabilities. The same weaknesses to the same pathogens.
This has happened before. Before the Cavendish, the dominant commercial banana was the Gros Michel — widely considered to taste better. In the 1950s, a soil fungus called Fusarium oxysporum cubense, commonly known as Panama disease, swept through banana plantations worldwide. Because every Gros Michel plant was genetically identical, the pathogen found no resistance anywhere. The Gros Michel was commercially extinct within a decade.
The Cavendish replaced it because it was resistant to that particular strain of Panama disease. But a new strain — Tropical Race 4 — is now spreading through Cavendish plantations across Asia, Australia, Africa, and Latin America. Because every Cavendish is genetically identical, it too has no natural resistance variation to draw on.
The Food and Agriculture Organisation of the United Nations has documented this threat. Researchers are looking for solutions. The primary constraint they face is that the Cavendish cannot be bred through seed to develop resistance. It can only be cloned. The same property that made it convenient to produce made it impossible to adapt.
This is not a hypothetical warning. It is a documented, active threat to the food security of a fruit that billions of people depend on. And it is a direct consequence of building a food supply around sterile, seed-free plants.
Who Controls the Seeds That Remain
The seedless fruit question sits within a much larger story that receives significantly less coverage than it deserves.
Four corporations — Bayer, Corteva, ChemChina-Syngenta, and BASF — now control more than 50 percent of the global seed market. Bayer, which completed a $66 billion acquisition of Monsanto in 2018, owns roughly 23 percent of the global seed market and 15 percent of the global agrochemical market. Corteva Agriscience owns 19 percent of the global seed market. Three corporations together control approximately 60 percent of the world's patented seeds, according to analysis from Corporate Europe Observatory.
This consolidation happened over decades through a series of mergers and acquisitions that individually attracted attention and collectively reshaped the foundation of the global food system.
The mechanism of control is the patent. Seeds have been patentable in the United States since a 1980 Supreme Court decision opened the door to patents on living organisms. Since then, the legal infrastructure around plant patents has expanded significantly. Corporations patent not just seed varieties but genetic traits, breeding methods, and the biological processes involved in creating specific plant characteristics. Corteva alone has applied for more than 1,400 patents on new GMO-related technologies, according to Corporate Europe Observatory's 2022 report.
The practical consequence for farmers is this: seeds under utility patent cannot be saved, replanted, shared, or sold. A farmer who buys patented seed must buy new seed every year from the corporation that owns it. The practice of seed saving — which is how agriculture fed human beings for ten thousand years — becomes legally prohibited under these patents.
The Center for Food Safety has documented that Monsanto — now Bayer — filed hundreds of lawsuits against farmers for alleged seed-saving violations, including cases where patented varieties had drifted into fields through natural wind pollination without the farmer's knowledge.
Sixty percent of the world's seed supply is owned by just four chemical companies, according to the Non-GMO Project's research. The same companies control the pesticide market. They engineer seeds to require their own branded chemicals, creating what Farm Action describes as technology packages — arrangements that lock farmers into buying both the seed and the chemical inputs from the same corporation every single year.
What This Has to Do With Your Watermelon
The seedless watermelon on your plate and the corporate consolidation of the global seed market are not separate stories. They are expressions of the same logic applied at different scales.
At the scale of a single fruit, the logic is: remove the seed, make it convenient, sell more of it. At the scale of an industry, the logic is: control the seed, patent the trait, make farmers dependent, profit indefinitely.
The biological result of both is the same. Plants that cannot reproduce without human — and specifically corporate — intervention.
When a home gardener buys a seedless watermelon from a supermarket and tries to save seeds to grow next year, there are no seeds to save. When a small farmer tries to source non-patented seed varieties to maintain independence from the major agrochemical corporations, they find an increasingly narrow range of options. The International Institute for Sustainable Development noted in its assessment of the Bayer-Monsanto merger that shrinking seed diversity threatens biodiversity, which is critical for enabling plants to withstand diseases, pests, and climate change.
This is the structural risk that the seedless fruit story points toward. Not that seedless grapes are individually dangerous. But that the direction of travel — toward sterile, non-reproducible, corporate-dependent food — reduces resilience at every level. For the individual who cannot grow their own food. For the farmer who cannot save their own seeds. For the global food system that cannot adapt to a new pathogen because the plants it relies on have no genetic variation to draw on.
The Numbers Behind the Consolidation
Some figures are worth sitting with directly because the scale of what has happened in the global seed industry is not widely understood.
In 1996, there were approximately 7,000 independent seed companies globally. By 2018, following waves of mergers and acquisitions, that number had declined dramatically. Just four companies now dominate a market that once had thousands of participants.
Bayer and DowDuPont — now Corteva — controlled 75 to 80 percent of the US corn and soybean markets by 2018, according to market analysts. Roughly 95 percent of all corn and soybeans planted in the United States are genetically engineered, with the top companies responsible for most of those sales.
In the European Union, a 2017 legal study concluded that competition law should have required the blockage of the Bayer-Monsanto merger, citing five factors: high market concentration, entrenched market power, reduced innovation incentives, elimination of a major competitor, and the ability of the merged entity to engage in price increases across both seeds and chemicals.
The merger proceeded.
Farm Action, an agricultural policy organisation, describes the current situation directly: the result is a food system where the most basic input — the seed — is controlled not by the farmers who plant it, but by corporations that profit from keeping them dependent.
What Is Being Lost
When a seed variety disappears from circulation — because it is unprofitable to produce at scale, because it has been replaced by a patented variety, or because it was simply never commercialised — it is generally gone. The genetic information it contained, accumulated through thousands of years of natural selection and human cultivation, does not exist anywhere else.
The FAO estimates that 75 percent of the world's crop diversity was lost during the twentieth century. In the United States, the National Seed Storage Laboratory found that approximately 93 percent of vegetable seed varieties that existed in 1903 are no longer available. The tomato varieties available in 1903 numbered in the hundreds. Most supermarkets today offer two or three.
This loss is not about sentiment. It is about the genetic toolkit available to humanity for adapting food crops to changing conditions. A diverse seed population contains millions of years of accumulated adaptations — to drought, to heat, to specific soil types, to specific pathogens. Every variety that disappears takes some of those adaptations with it permanently.
The seedless fruit trend and the corporate consolidation of seeds are together accelerating this narrowing. The diversity of what is grown commercially is declining. The diversity of what is patented is concentrating. The diversity of what ordinary people can grow from seed — in a pot, in a garden, on a rooftop — is shrinking, one sterile clone at a time.
The Case for Seeded
None of this is an argument that seedless fruits are poisonous or that the companies producing them are engaged in outright conspiracy. The biology of parthenocarpy is real. Some seedless varieties emerged from natural mutations. The convenience is genuine.
The argument is simpler and more structural. A food system built around plants that cannot reproduce is a food system that requires corporate mediation at every step. Seeds must be purchased. Varieties must be licensed. Crops must be grown from proprietary stock. The farmer, the home grower, the community garden — none of them can close the loop without going back to the corporation that holds the patent or controls the variety.
That dependency was not inevitable. It was built, policy by policy, merger by merger, patent by patent, over several decades by a small number of very large corporations that understood, long before most consumers did, that whoever controls the seed controls the food.
The person who grows a tomato from a saved seed, plants a chilli from fruit bought at a market, or propagates a herb from a cutting, is doing something that has been made deliberately harder over the past fifty years. Not illegal in most cases. Just inconvenient, less available, less supported, and less visible than the alternative being sold to them at every supermarket.
It is worth knowing that. And it is worth deciding what to do about it.
