Fig/Mulberry/Breadfruit/Jackfruit are all in the same family.
They all do well with just rooted cutting without any taproot, even with typhoons pasting thru.
I have personally rooted and grown quite a few of them.
Just like breadfruit grown from cutting it will develop a wonderful
root system and do well, my only worry is that it will take a while before you will be able to harvest it.
Also transplant the cutting before it has grown more than 5 leaves even better if it only has only grown 3 leaves.
One tip is to bury it as deep as possible even a leaf or two.
Even better plant around 7 or so in the same hole and then train them to merge into one tree for earlier fruiting.
Most of my jackfruit exposure has been with the soft and sweet type and not with the open with a knife types, but there shouldn't be much of a difference.
