Rainbow of potential alternative pomegranate varieties
Almost all pomegranates grown in the United States are one variety: Wonderful. John Chater, a Ph.D. student at the University of California, Riverside, wants to change that.
He would like to broaden the varieties of pomegranates available so that someone going to a supermarket can, like apples, buy varieties of pomegranates that vary in sweetness, seed hardness, flavor profile and color.
With that in mind, he has spent the last four years researching the commercial potential of 13 pomegranate varieties, and also started breeding new types of pomegranates.
He has field trials set up in Riverside and Somis, just east of Ventura, so he can evaluate the difference between coastal and inland climates. He has also chemically analyzed the juice of the varieties for quality.
Preliminarily, Chater, who is a 2016 University of California Global Food Initiative student fellow, has identified seven pomegranate varieties that have commercial juice potential. Three of them – Blaze, Phoenicia, and Purple Heart – were developed by his grandfather, who was a mechanic at a hospital but developed a cult following among fruit growers in California for developing new varieties of pomegranates.
Here are some of the pluses and minuses of each variety compared to Wonderful:
Al Sirin Nar: Large fruit, with hard seeds, soft peel, and large arils. With its sweet-tart juice, it could be useful for juice applications. Seeds may be too hard to be sold as a whole fruit.
Blaze: Medium sized fruit, juice more sweet than tart. Fruit similar to Wonderful. Could serve coastal and inland growers. Has potential to be sold as a whole fruit.
Desertnyi: Soft-seeded, medium sized fruit with ornamental quality. Delicious balanced flavor that has been described as citrus-like. Trees seem to may need trellis or rootstocks for commercial production. Has potential to be sold as a whole fruit.
Parfianka: Soft seeded variety with sweet-tart to sweet flavor. Very precocious in the field and on both inland and on the coast. This variety is an international favorite for its refreshing flavor and soft seeds. Has potential to be sold as a whole fruit.
Phoenicia: Large fruit with medium to hard seeds. Fruit multicolored with yellow, pink, and reds. Sweet-tart flavor with a tartness that consumers enjoy. Fruit seems to keep well in storage.
Purple Heart: Medium-sized red fruit that has dark red juice and arils. Fruit and juice similar to ‘Wonderful'. Sold as ‘Sharp Velvet' at Dave Wilson Nursery.
Sakerdze: Large fruit, with hard seeds, soft peel, and large arils. Juice is sweet to sweet tart. Fruit can be pinkish to red.
