Grapes without seeds, GMO or non-GMO
Let's clarify one thing immediately: the main varieties ofseedless table grapesavailable today, they are NOT GMOs, that is, they have not been genetically modified to be seedless but are the result of very ancient crosses.
L'seedless table grapessees varieties already known in the second half of the last century.
The varietySultana grape, very widespread all over the world both for its fresh consumption and in the form of raisins, is among theseedless table grapesmost popular.
In the second half of the last century, crossing thetable grapesand from seedless wine with fine grape varieties with seeds, varieties were born parthenocarpic, that is, completely seedless, of excellent quality. Let's not talk about fruit genetically modified, but of varieties obtained by winemakers, selection after selection.
Seedless grapes, properties
Thenutritional properties(calories, intake of micronutrients, sugars ...) ofseedless grapesthey are the same as grapes with seeds.
In addition to the good ones property typical organoleptic characteristics of table grapes (skin color, sugar content, presence of aromas in the pulp ...), the varieties ofseedless grapes, sees grapes of good size, regular clusters that do not clump and thus reduce the risk of contracting fungal diseases or rot.

In theseedless watermelon, the number of chromosomes is first doubled by the use of the chemical colchicine, by doubling the chromosomal set of a normal watermelon (which is diploid) we obtain a tetraploid plant (four pairs of chromosomes). By crossing a tetraploid watermelon created in the laboratory and a diploid watermelon, a triploid plant is obtained which gives life to seedless watermelons,which is thus a barren fruit.
