Seedlessness is an important feature of some fruits of commerce.
Commercial cultivars of bananas and pineapples are examples of seedless fruits.
Some cultivars of citrus fruits (especially navel oranges), satsumas, mandarin oranges, table grapes, grapefruit, and watermelons are valued for their seedlessness.
In some species, seedlessness is the result of "parthenocarpy", where fruits set without fertilization.
Parthenocarpic fruit set may or may not require pollination but most seedless citrus fruits require stimulus from pollination to produce fruit.
Seedless bananas and grapes are triploids, and seedlessness results from the abortion of the embryonic plant that is produced by fertilization, a phenomenon known as "stenospermocarpy" which requires normal pollination and fertilization.
A seedless fruit is a fruit developed to possess no mature seeds.
As consumption of seedless fruits is generally easier and more convenient, they are considered commercially valuable.
Most commercially produced seedless fruits have been developed from plants whose fruits normally contain numerous relatively large hard seeds distributed throughout the flesh of the fruit. 
Kinnow fruits have more seeds per wedge than other citrus fruits.
The high seed content of this variety is a major hindrance in out-of-hand eating.
Some workers have made efforts to select seedless kinnows by survey or by the use of mutants.
The seeds of kinnow are naturally diploid or tetraploid.
Seedless triploid varieties have been developed, but these are still undergoing testing to ascertain whether the fruit is healthy for consumption. 
Seedless grapes are divided into white, red and black types based roughly on fruit color.
The most popular seedless grape is known in the United States as 'Thompson Seedless', but was originally known as 'Sultana'.
It is believed to be of ancient origin.
It is considered a white grape, but is actually a pale green.
Other white cultivars are 'Perlette', 'Menindee Seedless', 'Interlaken', 'Himrod', 'Romulanus', 'Lakemont', 'Fayez', and 'Remailey Seedless.'
The most popular red seedless in the U.S. is 'Flame Seedless'.
Other red cultivars are 'Crimson Seedless', 'Ruby Seedless', 'Suffolk Red', 'Saturn' and 'Pink Reliance'.
Some black cultivars are 'Black Beauty', 'Black Monukka', 'Concord Seedless', 'Glenora' and 'Thomcord.'
Stenospermocarpy is the biological mechanism that produces parthenocarpy (seedlessness) in some fruits, notably many table grapes.
In stenospermocarpic fruits, normal pollination and fertilization are still required to ensure that the fruit 'sets', i.e.
continues to develop on the plant; however subsequent abortion of the embryo that began growing following fertilization leads to a near seedless condition.
The remains of the undeveloped seed are visible in the fruit.
The fruit of seedless grapes is smaller than normal because seeds produce the plant hormone gibberellin, which causes fruit enlargement.
Most commercial seedless grapes are sprayed with gibberellin to increase the size of the fruit and also to make the fruit clusters less tightly packed.
A new cultivar, 'Melissa', has naturally larger fruit so does not require gibberellin sprays.
Grape breeders have developed some new seedless grape cultivars by using the embryo rescue technique.
Before the tiny embryo aborts, it is removed from the developing fruit and grown in tissue culture until it is large enough to survive on its own.
Embryo rescue allows the crossing of two seedless grape cultivars.
