Some months ago I cut down a few banana trees which had fruited and were generally deteriorating. I left stumps approx. 30cms high and expected them to rot away. Now I notice that they all have put out new shoots and leaves, in some cases a metre high.

Can I expect them to grow up and produce more fruit?

 

Banana trees fruit and then die.

New trees grow from the old trees roots.

To clarify, the new shoots are coming from the centre of the old stumps. Will they bear fruit in the future?

I've never allowed that regrowth from the center to mature, I keep cutting it out until it gives up, in order to favor selected off-shoots, which are always dependable. I'm not sure, but I've assumed that the re-growth would not produce or would be inadequate.  Hopefully someone will be able to answer your question. 

 

The regrowths are not as strong as new shoots will be and may break under the weight of fruit. Best practice is to cut them back to encourage faster growth of new shoots. Each root mass and its associated stems are actually one plant, so you are not losing anything.

If it already has produced fruit ,the new shoot will grow ,but it will not be a strong plant,and could well die, and will not produce any new fruit.
