Can you California avocado growers please help me ID this Avocado?

[weiss613]

Maybe you can help me ID an avocado I brought back 5 years ago from Persea nursery just north of San Diego 5 years ago that has since closed.
I brought back 5 Carmen’s in 1 hard cover Samsonite suitcase to Miami.  One of them grew 6 Times faster Than the other 4 trees. 2 years ago the tree was about 20 feet tall and loaded with fruit but a hurricane blew them off. Last year zero fruit. This year loaded with fruit and then holy crap around December they started turning black. These were not Carmen’s because they were looking like Florida avocados. The last one was picked last week. It was 2 lbs 1 Oz. Average size was about 4-5 ounces less. With smooth black skin. This tree was not a grafted tree because upon examination of the trunk there is no sign of a graft and the diameter at the base of the tree is 4 x’s The size of my Carmen’s.  It may be a new variety but one of you might actually know what it is. It was tested for dry weight and it was 26%. Thank you for any help.

How could we ID it if its not grafted?   Is there a bump runing up and down the length of the fruit on one side?  Kind of looks like Sir Prize but if its not grafted then ?

Cut it open post a pic.

It's all speculative, but it appears similar to 'Queen'.

Queen is a Guatemalan x West Indian selection from Antigua. It bears in the time-frame one would expect for such a cross, around the end of the year.

I don't have first-hand experience with this cultivar other than killing a tree, but the fruit are said to be large, rich, and delicious.

If yours is a seedling, it appears to be a decent selection.

It's not Queen. 

Skin too smooth, and wrong shape and color.  Queen is rougher skinned, longer and pear shaped, and has a slight tint of red/purple.

Wrong shape for Sir prize.

Through much research and many calls to nurseries in Fallbrook California I found the guy that bought the nursery that I bought the tree from. This is an amazing story. I bought 5 Haas Carmen’s. One was different. It grew 6 times as fast as the other 4. The fruit didn’t look like a Hass.
It was a seedling that the graft of Carmen didn’t take. Yet the tree was 20 feet tall in 3 years and fruited heavily. 
The answer is it was clonal rootstock vc 801 from Israel. It is the best rootstock for saline earth and cold. It makes a fantastic Avocado with 26% solids.

wow, clonal rootstock quite amazing! can you show a pic with the fruit cut open?
most important how's the taste?

[weiss613]

Out of 10 it's an 8.5 taste and texture. Has a big seed great for seedlings.

for some reason it won't let me add the image

Interesting Weiss, thanks for reply bummer yo can't load pic!

You can pass out scions to do clonal at home.

[weiss613]

That is a fascinating idea. What do you do?
Do you take a scion and put it in water to get roots then just plant it?
