Talking about the Atta series specifically (Cherimoya, Sugar Apple, Custard apple, llama, Poshte I think)
From the old research papers, industry practices, and even forum members' experiences, Cherimoya seems to be the most compatible.
Sugar apple works too but it seems to impart less vigor on the trees. I haven't seen much success with Custard apple but it isn't studied much. (I would love if it worked)
Varieties differences play a role too
Pond apple does sort of work as a rootstock but we have seen long term incompatibility with various species (Atemoya, Illama, Dream)
I personally would want to sell something that requires my customer to constantly strip off suckers.
Again the variety matters here too.
One route to explore is using interstocks
ZHPP was selling San Pablo on A. Glabra, I plant one two years ago, and not one rootstock sucker emerged.
My atemoya which was planted at the same time (on pond apple) is still only two feet and suckers a lot.
We'll see how Cherilata works long on Pond apple over the next few years.
I figured recticulata interstock is worth a try
There are quite a few of us on here experimenting with annonas here so maybe we'll hear of some good news in the coming years
This is all based on South Florida conditions
