The term "sultana" refers to golden-colored dried grapes, which may also be called "golden raisins" (such as marketed by Sun-Maid, a California-based raisin grape growers' co-op and legacy brand). Any grape may be used to produce golden raisins, and any kind of golden raisins from any kind of grape may be marketed as "sultanas".
The seedless plant combines male sterility in the pepper plant (commonly occurring) with the ability to set seedless fruits (a natural fruit-setting without fertilization). In male sterile plants, the parthenocarpy expresses itself only sporadically on the plant with deformed fruits.
A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes are a non-climacteric type of fruit, generally occurring in clusters. The cultivation of grapes began approximately 8,000 years ago, and the fruit has been used as human food throughout its history.
The pollination and fertilization of grapes results in one to four seeds within each berry. When fertilization does not occur, seedless grapes are formed, which are sought after for the production of raisins. Regardless of pollination and fertilization, most plants will produce around 100 to 200 grapes. [33]
Seedless varieties include sultanas (the common American type is known as Thompson Seedless in the United States), Zante currants (black Corinthian raisins, Vitis vinifera L. var. Apyrena), [3] and Flame grapes. Raisins are traditionally sun-dried but may also be artificially dehydrated.
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. [2] Grape breeders have developed some new seedless grape cultivars by using the embryo rescue ...
This list of grape varieties includes cultivated grapes, whether used for wine, or eating as a table grape, fresh or dried (raisin, currant, sultana).For a complete list of all grape species, including those unimportant to agriculture, see Vitis.
Grapes can be eaten fresh or dried to produce raisins, sultanas, and currants. Grape leaves are used in the cuisine of many cultures. The fresh grapes can also be processed into juice that is fermented to make wine and vinegar. Cultivars of Vitis vinifera form the basis of the majority of wines produced around the world.
