Any chance you can identify this annonas only from leaves

[Orkine]

I started several seeds of cherimoya, custard apple, sugar apple and atemoyas, plus some mystery annonas seeds from past seasons.  I wasn't expecting much and planned on using them for rootstock.
One plant pushed well and really looked good so I set it aside.  Today it was the victim of kids playing and was snapped in two.  I will try to nurse the stump but wondered if anyone can suggest what this might be from the leaf which is unusual and unlike any of the others that germinated.






Some extra info
The seedling held leafs through our winter, but that may be because it's in a pot close to the house and was brought indoors for the coldest nights
It was about 18 inches tall when it met it's Waterloo at the hands of a errant volleyball.
The leaves are deep green and roundened.
No felt on the underside but soft and smooth to the touch on the upper side.

All suggestions welcomed.

I would guess atemoya but since I’ve never grown cherimoya I can’t rule that one out.

It looks like a Cherimoya. Atemoya leaves are more pointed (not round shape). Red Geffner Atemoya leaves are most pointed and slim.

See if this may help you https://www.horticulture.com.au/globalassets/laserfiche/assets/project-reports/cu11000/cu11000-final-report-complete-2.pdf on pg 15 they talk about leaf hairiness as a means of differentiation. The cherimoyas I’ve grown as rootstock and the grafted one I have for breeding are noticeably more hairy “felt” feeling. From the pics you posted I would lean more cherimoya.

Looks like Cherimoya.

Just a question question since you have just started annona from seeds.  I tried germinating cherimoya seeds for 3 weeks now and nothing comes up. 

How long did it take yours to germinate?

Thank you

Definitely looks like cherimoya

[Orkine]

I will assume it's cherimoya and graft something on the stump.
Thanks all

It is not Sugar Apple or Custard Apple. It could be Cherimoya or an Atemoya that leans strongly on its cherimoya parentage. Some Atemoyas look more like SA and others more like C. C types have wider internodes and grow faster. SA types make smaller trees.
