This triploid seed is the seed that produces seedless watermelons! In other words, a seedless watermelon is a sterile hybrid which is created by crossing male pollen for a watermelon, containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell.
Are seedless watermelon genetically modified?
Seedless watermelon is not a genetically modified food; it is a result of cross-breeding. The result is a watermelon with 33 chromosomes, and the tiny white seed husks don’t mature into fertile seeds and therefore is sterile.
How do you grow seedless watermelons if they have no seeds?
Seedless watermelons are triploid. They have three sets of chromosomes. This odd number results in them being sterile and not producing seeds. The way they become triploid is by mating a diploid male with a tetraploid female.
How do seedless watermelons propagate?
Seedless watermelons are particularly interesting because they must be propagated by seed, and yet growers can still exploit parthenocarpy. As in the case of bananas, triploid watermelons cannot produce functional seed, but they still develop good fruit through parthenocarpy.
Will seeds from a seedless watermelon grow?
Seedless watermelon fruit will have white seed traces, but only occasionally will it have a mature, brown, hard seed. Since the pollen of these plants is not viable, a diploid, seeded watermelon needs to be planted along with the seedless variety.
Where do they get the seeds to plant seedless watermelons?
When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant that is basically a “mule” of the plant kingdom, and it produces seedless watermelons. Seed of seedless varieties are available from most major seed companies.
Why does my seedless watermelon have black seeds?
The answer is “No.” Well, in his opinion, 99.99 percent of the time it’s “No.” The errant black seed that is sometimes found in a seedless watermelon is actually an empty seed coat that sometimes turns from white to black when stress — which can be environmental or chemical — is placed on the plant.
Do watermelons have seeds?
Watermelons, like all fruit, naturally produce seeds, but these days, the preferred type of watermelon is one that’s seedless. The traditional Western watermelon sports a green rind, red flesh, and black seeds, which are slightly bitter under their hard shell.
Are fruits without seeds genetically modified?
Seedless plants are not common, but they do exist naturally or can be manipulated by plant breeders without using genetic engineering techniques. No current seedless plants are genetically modified organisms (GMOs). All seedless fruit fall under a general category called parthenocarpy.
Which fruit has no seeds answer?
Common varieties of seedless fruits include watermelons, tomatoes, grapes (such as Termarina rossa), and bananas. Additionally, there are numerous seedless citrus fruits, such as oranges, lemons and limes.
How do you induce Parthenocarpy?
Parthenocarpy can be induced by exogenous applications of plant hormones. Most genes involved in fruit set are related to growth regulators of fruit development, such as gibberellins (GAs) and auxins (Ozga and Reinecke, 2003).
How can you tell if a watermelon is male or female?
The male flowers appear first on the plant and the female flowers follow a week or two later. It’s easy to tell the difference between the two. A male flower will connect directly to the vine while a female flower will have a bulb behind the flower. The bulb behind the flower looks like a miniature watermelon.
Can you still buy seeded watermelon?
While the seedless and mini varieties have taken over in popularity and demand, there certainly are still many folks who grow and sell the seeded watermelons, oblong in shape, chock full of black seeds.
Can you plant the white seeds from a watermelon?
The white seeds cannot be used to plant and grow a watermelon plant, as they are infertile, but both types of seeds are edible.
What is the best month to plant watermelon?
Plant watermelon from late spring to early summer, once soil temperatures reach 70° F or above. Space watermelon 3 to 5 feet apart in nutrient-rich, well-drained soil with a pH of 6.0 to 6.8.
What happened watermelon seeds?
When the eggs are pollinated, they create triploid cells These cells are capable of maturing into fruit, but the seeds in that fruit are not genetically viable – so they can’t be fertilized and develop the hard, black [seed coat].”Jul 26, 2012.

Do I soak watermelon seeds before planting?
Many types of plant seeds benefit from pre-planting soaking to soften the outer seed coating and hasten germination. However, watermelons are an exception to the rule. Soaking the seeds before planting increases the risks of various fungal diseases, such as anthracnose caused by the Colletotrichum lagenarium fungus.
Do you have to dry watermelon seeds before planting?
If you’re up for a challenge, or just curious, and decide to use seeds from a store-bought watermelon (or are using seeds from an open pollinated heirloom watermelon), you’ll need to dry the seeds before you plant them. Once they’re dry, you can plant them!.
How do you prepare watermelon seeds for planting?
Once the watermelon has cured, it’s time to remove the seeds. Cut open the melon and scoop the seeds out, flesh and all. Pour the “guts” into a large bowl and fill it with water. Healthy seed sinks to the bottom and dead (not viable) will float along with the majority of the pulp.
