Measured against each other
These two have never been grown in the same trial AMSeed holds. Every difference in the table above is a difference between what each variety's own sources say about it, which is not the same as a difference between the varieties. Two catalogs counting days from different starting points, or reporting fruit weight from different seasons and soils, can differ by more than the seed does.

Origins
Roma VF
The USDA-bred paste tomato that became a supermarket generic. Released from the Beltsville program in the 1950s, with the VF re-selection adding fusarium and verticillium resistance, one of the earliest mainstream examples of resistance breeding in a home-garden variety.
Plum Regal
A modern plum bred for sauce growers in blight country: full Ph-2 + Ph-3 late blight resistance in a determinate Roma-class fruit.
