Grapefruit as the ancestor of many citrus species
There are around 400 different varieties of the citrus family in the world, but only a few are known in this country. However, these are not always species in their own right, as many varieties are merely hybrids or crossbreeds. Backcrosses mainly from the grapefruit, mandarin and lemon-lemon species. These three types of citrus are among the original varieties, as is the kumquat.

Grapefruit as the origin of grapefruit and pomelo
In contrast, the grapefruit (in English: grape fruit) is a cross between grapefruit and orange. It originated in Barbados in the 19th century. Today grapefruit is cultivated worldwide in tropical, subtropical and Mediterranean climates. The main growing areas are Florida, the Philippines, the Caribbean Islands, Israel and South Africa. The pomelo, on the other hand, was created by crossing grapefruit and grapefruit.
Grapefruit - The largest of all citrus fruits
The original grapefruit produces the largest fruits: they can weigh up to two kilograms. The pulp of the grapefruit can take on quite different colors, whereby reddish or pink colored fruits usually taste sweeter. The striking color comes from the carotenoid lycopene, which accumulates in the pulp at very high summer temperatures. Real grapefruits have a sweet and sour taste, but they are also significantly more bitter than grapefruit.
Confusing species names
Although the three citrus fruits mentioned are different varieties, it is difficult to differentiate precisely - it is made difficult by a colorful jumble of languages. For example, the English name “grapefruit” is gradually displacing the name “grapefruit”, which originally came from Dutch, although it is not the same fruit. There is also great confusion in other languages:
- In English, the grapefruit is not called grapefruit, but pomelo.
- In Spanish, on the other hand, the grapefruit is called pomelo.
- Likewise in French.
