Avocado dusa et albaida
« on: February 02, 2022, 12:26:45 AM »
Some people have told me about the avocado dusa and albaida, which would be used as rootstock for heavy soils.

Do any of the members have experience of this, what do these rootstocks do in clay soil for example?
How long in clay soil can they withstand wet soil?
Do you know if any nurseries sell this kind of rootstock?

After searching the web, I have gathered various information about the avocado Dusa.
https://patents.google.com/patent/US20030051278P1/en
https://patents.google.com/patent/USPP15309P3/en
https://gregalder.com/yardposts/avocado-rootstocks-what-do-they-matter/
https://www.westfaliafruit.com/for-growers/our-rootstocks/

I am curious to know what members who use it as rootstock can tell me about it.

The nursery ( https://www.subtropicanurseries.com/ ) seems to use it, but I doubt if they can send it to Europe for non-professionals.

Yeah the dusa rootstock works awesome with hass variety.  Its super vigorous and rot tolerant.  Nurseries sell it here.  Not sure what else there is to say, the links you posted have all the info.

Its probably not going to do a whole lot for you if your weather and soil arent great.  It not a magic cure all.

Yes spaugh, I suspected that, but it's always interesting to get other opinions.

Fortunately in my case I don't have just 1 plot so not one soil type. This allows me to choose the ideal location. Even if I admit that having rootstocks that would allow me to plant such a crop on any type of soil would not displease me.

The question is also because some people are interested in it on another forum, that's the main reason for my question.

You could buy a tree grafted onto dusa and then lop it off below the graft line.  Otherwise, may be hard to get.  The nurseries that have it dont really share it.

The problem is that until recently you were forbidden to grow it outside the rules that the company holding the rights granted (because of the patent), which is rather normal.
Now, it remains to be seen if you can get some, since the patent seems to have expired.
But I don't know where you can buy scions.
Because as Spaugh says, it seems that nurseries still don't want to share him.

But Spaugh, can you confirm that it's okay to cut the grafted variety and let the rootstock grow to get scions?
Or do they still hold the right to forbid you to do that?

It's just a question to understand what possibilities they have to sue someone who would use their variety now that the patent has expired.
You probably know this better than I do.

I have no idea what the plant rules are.  Unless you are going to setup a million dollar cloning operation and sell thousands of trees, I dont think the plant police will come for you. 

You could do it an not tell anyone.
