The varieties of oranges that typically have no seeds or very few seeds include the navel and blood oranges. Navel oranges have thick skins and easily recognizable navel-shaped indentation, as well as very sweet, juicy flesh.
They are typically seedless, but some smaller navel oranges may contain a few, barely noticeable seeds. Blood oranges, usually more tart than regular navel oranges, also have few, if any, seeds. There are also some seedless varieties of Valencia oranges, although these oranges usually have some small, edible seeds.
Other hybrid varieties of oranges, such as the Minneola tangelo, may also have fewer seeds than most oranges, and some can nearly be seedless.

Do seedless oranges exist?
No, seedless oranges don’t actually exist. While most commercial oranges you find in the supermarket are seedless, this is due to a genetic mutation that makes the oranges unable to produce seeds. Citrus fruits with domed or lumpy shapes tend to have edible seeds, while smoother citrus fruits are typically seedless.
However, even seedless or smooth-skinned oranges may have some tiny, inedible seed remnants. Generally, commercial oranges are picked before they have the opportunity to develop mature seeds. So essentially, seedless oranges are a myth – the only true seedless citrus fruits are those that have the genetic mutation.
Which oranges are sweet and seedless?
Navel oranges are the most common type of seedless, sweet orange. Navel oranges are oblong in shape and usually have a distinct navel-like end, which is caused by a second, smaller fruit growing into it.
They have a thick, bright orange skin and are usually seedless. The flesh is sweet, juicy, and easy to eat. Other common types of seedless, sweet oranges include Valencia and Murcott oranges. Valencia oranges are also oblong in shape and have a bright yellow or orange skin but they are smaller and slightly more acidic than navel oranges.
Murcott oranges have a smooth, deep orange skin and have a mild sweetness that is a nice balance between a navel orange and a Valencia.
When did oranges become seedless?
Oranges have been cultivated for centuries, but the development of seedless oranges didn’t begin until the late 19th century. In 1916, two varieties of seedless oranges, Satsuma and Rohde Blood, were introduced to the United States.
By the mid-1960s, the navel orange had become the most popular variety of seedless oranges and is still the most popular today. Although oranges were grown in California as early as the mid-1800s, it was not until the early 20th century that seedless oranges became a common feature of the California growing industry.
During this time, a variety of seedless oranges were developed including the navel orange, Fremont mandarin, Blood orange, and Valencia orange. These varieties of seedless oranges are still popular today and make up the majority of oranges grown in California.
How many seeds does an orange have?
The number of seeds an orange has can vary from 0 to over 10. It depends on the variety/type of orange. For example, Valencia oranges typically have fewer than 10 seeds, while navel oranges often have around 6 to 8 seeds.
Additionally, some oranges are seedless, meaning they have zero or almost no seeds. So the answer to the question depends on the variety of orange in question.
Is a seedless orange genetically modified?
No, a seedless orange is not genetically modified. Instead, it has been developed through the process of citrus breeding. Citrus breeding is a process in which the natural variation that exists within several types of citrus plants is used to create new varieties.
This process has been used to create seedless oranges and was accomplished by crosspollinating two varieties of oranges. One of the varieties had a high level of sterility, meaning that it partially inhibits the production of seeds due to its chromosomal makeup.
This germplasm was then crosspollinated with other varieties of orange to develop a new variety that is more often seedless. Therefore, seedless oranges are not genetically modified, but the result of a natural breeding practice.
Are oranges naturally seedless?
No, oranges are not naturally seedless. While some varieties are seedless, oranges typically have between 10-20 seeds inside. Citrus fruit varieties like oranges, lemons, limes, and grapefruits usually have seeds inside.
Breeding has enabled the production of seedless varieties of oranges, but these are not the same as being naturally seedless. In order for fruit to be naturally seedless, the seeds must be absent from the plant’s genes, which is not the case with oranges.
The existing seeds of oranges, while often small and well-hidden, are still present and are theoretically capable of propagating new plants. That isn’t to say that seedless oranges can’t be planted, however; many gardeners have achieved success by starting seedless oranges.
Is seedless fruit fake?
No, seedless fruit is not fake. Seedless fruit is created through various genetic processes that allow for fruit to be born without seeds. The most common type of seedless fruit is watermelon, but many other varieties of seedless fruit can be created through the same natural selection process.
Seedless fruits are real and can be found in grocery stores and markets around the world. Seedless fruits have become quite popular in recent years as they offer a convenient alternative to seeded fruits, as they do not require any additional preparation prior to consumption.
While seedless fruit may be slightly different from its seeded counterparts, it is nevertheless still a genuine form of fruit and provides the same nutritional benefits.
How do you grow seedless oranges if they have no seeds?
If you are looking to grow seedless oranges, the most common technique used to do so is called asexual propagation, also known as grafting. It involves taking a branch or twig from a citrus tree that is already producing seedless oranges, and cutting it into sections.
Each section is then grafted onto the stock of another tree, which will serve as its root system. As the branch eventually takes root, it will begin to grow and produce new fruit. This process will ensure that the new fruit will be seedless, just like the original tree.
Other techniques for growing seedless oranges can include chemical treatment and air layering, but these usually produce fruits with a lower quality and are often not recommended.
