I wonder why you all repeat what I said ...

Well, I know that Double Fina is a Washington seedling ... research and the UNKNOWN will change to KNOWN ...

Radoslav,
In the article on the origin of blood oranges that you posted before they state:
Our
molecular analyses showed that Sanguinelli, which is a derivative
of the Spanish Doblefina, shared a common origin with Sicilian
blood oranges.
It has nothing to do with Washington.

By the way... did you know this (excellent!) juice?

Of course !

Just that´s for out of the season, now I press myself fresh juice ...
Nothings is better ...

Ok, you GENIUS ...

One lil question:

Why you think it is called WASHINGTON Sanguine ???

Think some days about it, maybe EVEN YOU get it then ...

NOTE: I don´t have to paste and copy what´s on a homepage, I know it MYSELF and I know MORE !!!

Sanguinello, this is what UC Riverside Citrus Variety Collection has to say about the Washington Sanguine:

http://www.citrusvariety.ucr.edu/citrus/washingtonsanguine.html

No relation at all to the Washington Navel. Sometimes trees will get names that in the end, have no relation whatsoever to its parentage or lineage. Like the Cocktail grapefruit, as it is commonly called, as well as commonly advertised and sold in my area. It has no grapefruit in it at all, but is a hybrid between the Siamese Sweet pummelo and Frua mandarin. But no one here in California ever refers to it as a "pummelo hybrid". It is always called a grapefruit, even though it has no grapefruit at all in its makeup. Seems to be the case with the Washington Sanguine.

I think what folks are wanting are your sources? If you can provide a link to your source that backs up what you're saying, then folks can review and evaluate.

This reminds me of Sanguinello.

My knowledge is far too vast and too special to find some info about it in internet always for you.

I am fed up and just will not share my knowledge any more with you.

Thank you!

Sanguinello, I think when anyone (including you, who have vast knowledge) is asked to support their comments, it's a reasonable request. I can't find anything out there that supports the statement that this variety is a seedling of the Washington navel orange. When others on our forum have been asked to provide supporting documentation to back up or support a comment or statement, they don't take offense, but simply provide links to support documentation or research. A perfectly acceptable request to "back it up with the facts". I check Jorma's site, and he, too, states that this cultivar is a varient of Doblefina, and in fact, is not at all related to the Washington navel:

Quote:

Washington Sanguine, a variant of the Doblefina blood orange, was found at Sagunto, Valencia province, Spain. As with most blood oranges, pigmentation development is variable. The fruit usually have only slight traces of "blood" inside. One of the traits of Washington Sanguine is that it can sometimes develop darker shades on the skin in suitable conditions while the flesh inside remains "bloodless" or has only a few specks. In spite of the name it is not related to Washington Navel orange.

Don't be offended, just provide your backup sources. Or, if you've made a boo boo, it's okay to say that, too! I've made plenty of them on this and other forums, and just state that. Sometimes all that information rattling around in my head can get a little jumbled up!
