Can it be a navel ?

Cara-cara Navel?

It's not a cara cara, but a Sokotoro blood orange.
I believe sokotoro is not a navel orange, but i have a doubt...

You're right. The pigmentation is pronounced, so indeed it is a pigmented orange. The one on cara-cara, altough the color looked the same from a distance, is more uniform.

Cara cara pigment is lycopene ( and maybe carotene ? ) , and most blood orange pigment is antocyanins ?

Is Sokotoro just a local name for the orange, and not an actual varietal name? I look up Sokotoro Blood Orange in the World Citrus Dictionary Vol. -2, and the name is not listed. - Millet

Seems it is a bud sport of Valencia. Have a look here http://translate.google.com/translate?hl=en&sl=fr&u=http://www.corse.inra.fr/sra/30100407.htm&sa=X&oi=translate&resnum=1&ct=result&prev=/search%3Fq%3DSokotoro%2Borange%26hl%3Den%26safe%3Doff%26sa%3DG

Yes, I knew the link, but i have never found any information about sokotoro nowhere else.
I've bought the tree in a nursery here, and the fruit are now mature. They are easy to peel.

It's a very good idea, but I don't really know enough words to describe a fruit !
I can just say that this orange is easy to peel, early maturing, seedless...

If you can send me some fruits, I'd gladly describe them for you!

but that won't be allowed unless you have to go through the eye of a needle in terms of regulations on importation and exportation.

Who is the supplier of this variety? Joe, their is a red Valencia that I believe is available here in the States. Is the Sokotoro the same variety? - Millet

Millet, I have not come across the Red Valencia being referred to as Sokotoro. As far as I know, the Red Valencia is a selection from within California. Red Valencia is now named as Red Smith and is grouped together as the other blood or pigmented oranges because the harvest date is no longer the same as any of the other Valencias.

History: Smith Red is a pigmented sport of a conventional Valencia orange tree. The mother tree was growing in a home garden in Moorpark, CA, and a branch was observed to be producing fruit with a pronounced red rind blush and strong red internal color. Seeds were saved from a fruit sample and brought to the local farm advisor, N Sakovich. The seeds were germinated and the most promising seedling was selected for release.

Characteristics: The tree is a vigorous grower and carries good crops of fruit. The fruit is of good size and flavor and is very low-seeded. As noted above, the rind frequently carries a heavy red blush and the flesh is heavily pigmented by anthocyanin. The fruit shape is somewhat variable at present, globose to ovoid with a depressed base, possibly due to the juvenility of the subject trees. Although the fruit is mature in late winter, it holds well on the tree into late spring, well past the season for conventional blood oranges.

Thanks for posting the pic Laaz!

Take note the name RED VALENCIA, it one and the same set of pics used for displaying Smith Red in this Link:

Thus, all evidences point out that Smith Red = Red Valencia.

I have grouped Red Valencia or Smith Red as blood oranges long before UCR regrouped it. My evidence is that I have grafted it unto my Pigmented orange tree about 3 years ago. Last year's fruits were aborted, but this year, I have BIG MEAN BRANCHES from my Smith Red and hope to savor it about same time next year. I'm counting the eggs now, not the chicks.
