Which Method Is Used To Obtain Seedless Watermelon?

So, the correct answer is ‘Somatic hybridization‘.

How do you get a seedless watermelon?

To produce a seedless watermelon, a chemical process is used to double the number of chromosomes. So, 22 chromosomes are doubled to 44, called a tetraploid. Then, the pollen from a diploid is placed on the female flower of the plant with 44 chromosomes.

How are seedless watermelon propagated?

Seedless watermelons are particularly interesting because they must be propagated by seed, and yet growers can still exploit parthenocarpy. One way to make seedless watermelons is to produce triploid seed.

What is a seedless watermelon called?

Seedless varieties include Chiffon and Honeyheart. As you may have guessed, depending upon the variety, flesh is yellow to orange in color. These melons mature in about 75 days.

What is Kihara technique in watermelon?

Tetraploid Production. Use of triploid hybrids has provided a method for production of seedless fruit. The tetraploid method for seedless watermelon production was invented by H. Kihara. He began development of tetraploids in 1939, and had commercial triploid hybrids available 12 years later.

How do we make seedless fruit?

Seedless fruits can develop in one of two ways: either the fruit develops without fertilization (parthenocarpy), or pollination triggers fruit development, but the ovules or embryos abort without producing mature seeds (stenospermocarpy).

Is seedless watermelon genetically modified?

Seedless watermelon is not a genetically modified food; it is a result of cross-breeding. The male pollen of a watermelon, containing 22 chromosomes, is crossed with the female watermelon flower, which has been chemically altered to contain 44 chromosomes.

Are seedless watermelons natural?

The answer is no. There is no such thing as a GMO watermelon. Instead, seedless watermelons are hybrid plants that are created by cross-pollinating a male watermelon with a female watermelon flower. Seedless watermelons were first produced by a plant geneticist named O.J. Eigsti in the 1940s.

Why do seedless watermelons have seeds?

Seedless watermelons are hybrid watermelons whose seeds are incapable of maturing into hard, black seeds, but that doesn’t mean they don’t try to produce seeds — the fruit does try, but because of this hybridization, the seeds can’t grow.

What are the types of parthenocarpy?

There are two types of parthenocarpy: 1) Agamospermy: This type of parthenocarpy occurs when an unfertilized egg develops into a seedless fruit. The fruit is genetically identical to the parent plant. 2) Apomixis: This type of parthenocarpy occurs when a seedless fruit develops from a nucellus that is not fertilized.

Who developed seedless watermelon?

Professor H. Kihara
The system for producing seedless watermelons was developed by Professor H. Kihara, a Japanese scientist at Kyoto University, who described his work in 1951.

What is the difference between seeded and seedless watermelon?

The Difference Between Seeded and Seedless Watermelon
The difference between the two is that while traditional, seeded watermelon contains hard black seeds, seedless watermelon has been bred to produce very soft and pliant edible seeds.

Is a seedless watermelon a fruit?

The answer is yes, a seedless watermelon is a fruit. However, it is in fact a hybrid fruit. Seedless watermelon are the product of cross-breeding a male watermelon pollen with 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell.

Which of the following is involved in seedless watermelon production Mcq?

So, the correct answer is ‘Somatic hybridization‘.

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. General Climatic Requirements.

What type of mutation is involved in the growing of seedless watermelon?

What describes the mutation that causes Epidermolysis bullosa? The mutation is caused by a change in one of the amino acids. Cumulative nature of scientific evidence. Watermelons are exposed to a mutagen to produce a variety that has four sets of chromosomes.

Which hormone does help to produce seedless fruit?

Strange as it seems, seedless watermelon plants are grown from seeds. The seeds are produced by crossing a diploid parent with a tetraploid parent to produce triploid seeds. When sprayed on flowers, any of the plant hormones gibberellin, auxin and cytokinin could stimulate the development of parthenocarpic fruit.

How do gibberellins produce seedless fruit?

Flowering also has an impact on the rate of fruit growth. Gibberellins are used in the production of seedless fruit such as seedless grapes, which are normally sprayed with gibberellin to increase the size of each grape.

When did seedless watermelon come out?

1939
Seedless watermelon production began its evolution in 1939. The first specimen was developed by Professor H. Kihara, a Japanese scientist at Kyoto University. Commercial triploid hybrids were available twelve years later, though they didn’t create a large market for themselves until the late 20th century.

Why are all watermelons seedless?

Watermelon plants are usually diploid, like us, meaning they have two sets of chromosomes, the packages of DNA with instructions for life. Seedless watermelons are triploid. They have three sets of chromosomes. This odd number results in them being sterile and not producing seeds.

Are seedless watermelons really seedless?

Seedless watermelons actually are not totally seedless. They contain white, edible seed structures like those in a cucumber. And under certain growing conditions a few hard, black seed coats will develop. Seedless watermelons are known in the trade as triploid watermelons; they contain three sets of chromosomes.
