The University of California, Riverside, has released Valentine, a hybrid that's part pummelo, part mandarin and part Ruby hybrid.

The fruit resembles a large grapefruit that has flesh similar to blood citrus, according to a grower newsletter.

It technically is a pummelo.

The name is derived from the shape of the fruit that when cut lengthwise and turned upside resembles a read heart.

The selections were part of crosses made originally in the 1950s that also resulted in Oroblanco and Melogold.

Valentine was described and evaluated by a group comprising Toni Siebert, museum scientist; Otillia Bier, staff research associate; David Karp, pomologist; Georgios Vidalakis; director of the Citrus Clonal Protection Program; and Tracy Kahn, curator of UCR's Citrus Variety Collection.

Valentine, originally known as pummelo hybrid 6C-28-18, is a cross among Siamese Sweet pummelo, Dancy mandarin and Ruby blood orange.

Fruit are round to slightly pointed, with the bottom being rounded and smooth.

Rind color is medium to dark yellow, with the flesh being red and seeded.

The fleshr is low in acidity, due to the pummelo parent, but it has a complex, floral taste from the Dancy parent. It matures in Riverside from January to March.

The red flesh contains anthocyanins, which have been coveted for their potential healthful benefits.

These are the same antioxidants contained in dark-colored fruits, such as pomegranates, blueberries and blackberries.
