All things being equal, I’ll defer to chickenlittle on which rootstock produces earlier.
That said, there are other factors you might want to look at if you want to bring your trees into production earlier. You can start by buying the biggest tree you can find. By that, I mean buy the largest caliper (diameter) tree you can find. Also, you can look for varieties that are “precocious” which means they tend to produce earlier than the norm. Ida Red, Florina, and Freedom are known to bear early (precocious). Norther Spy and Gravenstein are notorious taking a long time to bear fruit. Finally, almost all crab apples will bear early, sometimes too early. A lot of guys here pick all the apples off their crabs so that the energy of these young trees goes into producing tree growth, rather than growing fruit too early. What I am getting at is this… you can control how fast your orchard comes into production by looking several factors - including the rootstock you are selecting. Good luck!!
