I have a farm and interested to grow papaya in. Thanks for your effort.
We don't make vendor recommendations but seedless papayas are rare. They can be produced commercially with a specialized system. Here is more:

hermaphrodite that's bearing fruit that are seedless. Who do I contact if I wanted to give them information about the tree for their research?
Oops! It looks like a picture of yourself came through, rather than the seedless fruit!
I would contact your local extension service. This link will help you to find the closest one to you:
I'm in the sahel savannah Nigeria (Gombe state).
Sure! This can be done with quite a bit of practice. Here is an article that will help:

In the past I grew Papaya to a good size but here not easy to get fruit. I know how to tell male from female when they have flowers but is there a way to tell when they are one or two feet tall?
I could not find a source that said you could tell other than by looking at the flowers.
I can't upload photo. I can only do it with my I phone and to an email.
Papaya trees are not pruned because the main growing point is terminal. Branching would reduce fruit production. If you look at photos of papaya trees, there are no branches except for the leaf stems coming out of the top. Here is more in this factsheet below. You may want to consult your local extension agent for any ideas to curb growth if it is a problem.
The papaya grow from the top and the tree is top heavy and has already blown over in heavy wind. Side shoots are already there and have formed fruits at lower levels.
This is typical. These trees are hollow, and do not contain wood inside. Since they fruit from a single, apical, trunk- Any pruning that you do will reduce fruiting capacity. They will bear fruit from side branches, but at a significantly reduced capacity. These short lived specimens are quite different from your, usual, tree.

we live in northeast Florida and have a papaya tree that has lost its leaves after this winter. There is fruit but leaves not coming back. What to do?
They are hardy in your area so, unless you had a colder winter than usual, the leaves should return. Here are the most common problems affecting papayas. See if any of the symptoms mimic your tree's. I also included general cultural conditions to compare with your care. Hopefully these will give you some answers.
