Measured against each other
The table above is two descriptions placed side by side. Below are the trials that grew both varieties in the same ground, in the same season, measured by the same people. That is the only setting where a difference between them is something somebody observed rather than something we inferred.
Yield and Income of Fall Staked Tomato Cultivars in Eastern Kentucky
2009 · University of Kentucky research plots at Quicksand · Quicksand, Kentucky| Measurement | Amelia | Bella Rosa | What the trial concluded |
|---|---|---|---|
| Marketable yield | 19,097 lb/aca | 15,193 lb/aca | Not separated. The trial's own letters put both in the same group, so the 3,904 lb/ac difference is not a result. |
| Cull rate | 4.2 %def | 1.9 %ef | Not separated. The trial's own letters put both in the same group, so the 2.3 % difference is not a result. |
| Fruit weight | 8.0 ozde | 9.6 ozab | Bella Rosa was heavier, and the trial's letters separate the two. |
Superscript letters are the trial's own mean separation, not ours. Entries sharing a letter were not separated at the trial's significance level however far apart the two figures look, and where a trial published none we say the difference is untested rather than treating the arithmetic as the finding. Each block is one site and one season.

Origins
Amelia
The Harris Moran (now HM.CLAUSE) hybrid that gave southeastern growers their first dependable TSWV-resistant fresh-market tomato, changing production economics wherever thrips fly.
Bella Rosa
Sakata's heat-set southern slicer pairing TSWV resistance with dependable fruit set in Gulf-state summers.
