I have 5 mango trees so far in south Orange County:
LZ on turpentine rootstock - 4.5 years in ground, only ~4 feet tall with very slow growth, lots of panicles but poor fruit set so far. Lots of PM despite 2x fungicide applications. It only set 2 fruit last year of poor quality.
Coconut Cream on turpentine rootstock - 4.5 years in ground, 6-7 feet tall and very vigorous, tons of panicles but poor fruit set so far. Lots of PM despite 2x fungicide applications. It set zero fruit last year. :-(
Malika on turpentine rootstock - 4.5 years in ground, ~4 feet tall with very slow growth. However this tree has been heavily shaded until very recently (another tree was blocking its light). It has a number of panicles with flowers that are just beginning to open. No PM issues. No fruit last year.
Multi-graft tree I purchased from Frank ~2 years ago. It has Sweet Tart, Juicy Peach, Zinc, and Puneet. The tree overall has grown poorly with the ST and JP grafts are doing the best. Both are flowering now with no signs of PM. The other two grafts have done nothing.
I also have a LaVerne manila I planted 2 years ago which is now 5 feet tall and growing beautifully. It currently has 1 LZ graft I added last summer. No flowers so far. I'm planning on grafting a number of other varieties on to it this year if I can find budwood!
