Root stock for Ross Sapote graft

[SanDiegoCherimoya]

Hi,

Does anyone know what rootstocks are compatible with Ross Sapote? Would white Sapote be compatible?

Thanks,
Doug

Most pouteria should be fine. Mamey is most common, green sapote, lucuma, canistel.

Most times you buy a Ross in a nursery, it is on mamey.

White sapote is casimiroa edulis, a part of the rutaceae family, and not compatible.

White sapote (Casimiroa edulis) and Ross sapote (Potueria campechiana subsp. or Pouteria sp.) are not in the same (nor closely related) botanical family so they would not be graft compatible.

But, I believe Ross sapote is graft-compatible with eggfruit (aka canistel or yellow sapote, Pouteria campechiana) and potentially lucuma as your second best option

Thank you for clarifying

There was recently some discussion in buy/sell/trade about lucuma rootstock options and from this thread it sounds like lucuma, canistel, mamey, ross all close enough to be graft compatible.  Good to hear, I had grafted some excess lucuma scion onto a ross sapote seedling, and I still have some more I might graft onto my canistel.
