Much of what you want can be done with citrus trees growing in the ground. However, it is greatly different growing in a container. It is true that Flying Dragon is a dwarfing rootstock, but a container is just as dwarfing to a tree as a dwarfing root stock and even more, unless you transplant into a larger and larger and larger container. Grafting on citrumelo and then putting the tree in a container will take away the rapid growth you desire from a rootstock. My guess is that much of what you want to know about various rootstocks can be found on the Internet, BUT much of what your looking for will not apply to container culture. The best information on rootstocks (both commercial and new varieties) can be found on the "Florida Citrus Rootstock Selection Guide", published by the University of Florida, but once again applies to in ground trees, not container trees.
