Hello,

University of Vermont says this about Bud 9;

=====
Bud. 9 (does not tolerate wet soils)

Strong Points:

Promising new rootstock
35 to 40 % size of seedling
Very resistant to collar rot
Hardier than M.9


Weak Points:

Needs support
Moderately susceptible to fireblight and tomato ringspot virus
Drought susceptible
======

They list a number of rootstocks on their web page:

Later,
Tom
