Grey captions say what stands behind that particular figure. Breeding, growth habit and fruit characters carry no caption because they rest on the record's sources as a whole rather than citing their own; closing that gap is ordinary outstanding work, not a finished job.
The breeder attribution here is supported by Tomato Production and Cultivar Guides. These claims name their own evidence rather than resting on the record's source list as a whole, because a species that distinguishes a variety, or an attribution to a breeding programme, is worth being able to check on its own.
Origin & history
Sakata's heat-set southern slicer pairing TSWV resistance with dependable fruit set in Gulf-state summers.

Against the rest of the tomato database
Where this variety sits among every tomato we hold a comparable figure for. Position is not merit: earlier is not better than later, and hotter is not better than milder. Only cultivar-level figures are compared, never trial results, and maturity is only ranked against figures counted the same way.
earlier than 62% of the 258 tomatoes we hold a figure for. None of these figures state whether they are counted from sowing or from transplant, so they are ranked against each other on the assumption that suppliers use one convention, which is not something any of them says.
Trial results
What this variety did in published university trials. These are observations of a season, not properties of the seed, so they are kept separate from the measurements above and are never merged into them. Letters are each report's own mean-separation groups.
Across every trial
What each measurement rests on. A figure from one plot in one season and a figure seen repeatedly across sites and years are different kinds of evidence, so the weight is printed beside the number rather than left for the reader to count.
| Measurement | Observed | Evidence behind it | Level |
|---|---|---|---|
| Cull rate | 1.9 % | 1 observation from 1 trial, 2009 | |
| Fruit weight | 9.6 oz | 1 observation from 1 trial, 2009 | |
| Marketable yield | 15,193 lb/ac | 1 observation from 1 trial, 2009 |
Ranges span what was observed; no average is taken across trials. Where the trials measured differently or grew at different populations the figures are a spread across conditions, not one population, and the row says so.
Yield and Income of Fall Staked Tomato Cultivars in Eastern Kentucky
2009 · Quicksand, Kentucky · fall · published as "Bella Rosa"
| Measurement | Result | Method |
|---|---|---|
| Marketable yield | 15,193 lb/ac a | Diameter-class grading of breaker-stage fruit, Per-acre yield extrapolated from small research plots |
| Cull rate | 1.9 % ef | Diameter-class grading of breaker-stage fruit |
| Fruit weight | 9.6 oz ab | Mean fruit weight from plot counts and weights |
Each trial states its own limits, and they are worth reading before acting on any figure here. Yields in these reports are extrapolated from small research plots and run higher than commercial farms achieve; cull rates reflect the disease pressure of one particular season.
Production systems
Described as suited to
No source we cite says which production system this variety suits.
Grown in trials under
Grown in open field in 1 trial we hold. That records where the plants stood, not where the variety belongs; no other system has been tested here.
