Quick Questions- Grafting/Rot- Plums

Planning to learn to graft next spring and I have chosen my best freeloaders to practice on. Santa Rosa or Flavor Supreme.

Question- Flavor Supreme has extremely fast growth. Will that quick growth transfer to the scion?

Question-What plum varieties have some resistance to brown rot. By some I mean any at all.

Question- Will apricot graft to Flavor Supreme.
