Cocktail grapefruit for breakfast. Lots of seeds. Grapefruit-like with a bit more sweetness.

Turns out citrus are all part of hybridization. Also known as a mandelo:


A fairly large citrus fruit resulting from the hybridization of a frua mandarin and a sweet pomelo (hence 'mandelo'). Despite the common name 'cocktail grapefruit,' it is not actually a true grapefruit.


The mandelo was developed in the 1950s at the UC Citrus Experiment Station, but then escaped into public orchards. It is a yellow-orange fleshed tri-specific citrus hybrid between a 'Frua' hybrid mandarin ('Dancy' mandarin × 'King tangor')and a Siamese Sweet pomelo. This makes it 1/4 King tangor, 1/4 Dancy tangerine, and 1/2 Siamese Sweet Pomelo. It is named for its ancestors, mandarin and pomelo.


Mother of all citrus

Oranges, grapefruit, lemons and limes all descended from single ancestor

Oranges, grapefruit, lemons and limes are all hybrids, mixed and matched from 10 “wild” citrus species descended from a single Asian ancestor some eight million years ago, scientists said….

The Citrus Family Tree: Most of Your Favorite Fruits Are Designed Hybrids

The citrus family starts off with just three types of citrus: citrus medica, citrus maxima, and citrus reticulata, also known as citrons, pomelos, and mandarins. These three citrus species are native to South and East Asia, but in the last few million years or so, genes from these three types have combined and mutated and generally made their way across the globe resulting in thousands of types of wild citrus.
