Steven, I would expect that you can use any apricot cultivar that is 
comfortable in your area, and probably any seedling of such an apricot, 
as a rootstock for Tomcot, or any other apricot - if and only if your 
soil suits apricot roots.

If your soil is developed from clay or clay loam, I think your chances 
will be better if you use a plum type rootstock. I would not recommend 
Marianna for apricot, and I don't know anything about Citation.

The older plum rootstocks Brompton, St. Julien A, and Pershore Yellow 
Egg are considered compatible with apricot and peach. Or you could use 
one of them as an interstem on Myrobalan. You could probably develop one 
as a rootstock by budding or grafting it on P. tomentosa (Nanking 
cherry), P, besseyi (Western sand cherry) or P. pumila (Eastern sand 
cherry ) possibly including relatives P. susquehanae, P.cuneata and P. 
depressa, using it as a nurse root and planting with the union below 
ground. Of course this would take longer.
