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.
Origin & history
UF's hot-set successor generation: bred by Jay Scott's program to set full-size fruit under Florida heat, with resistance to all three fusarium races.

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 73% 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 | 2.6-75 % | 2 observations from 2 trials, 2009 Not combined: the trials measured this differently, so the figures are reported as a spread rather than combined. | |
| Fruit weight | 8.6-8.8 oz | 2 observations from 2 trials, 2009 Not combined: the trials measured this differently, so the figures are reported as a spread rather than combined. | |
| Marketable yield | 9,945-21,243 lb/ac | 2 observations from 2 trials, 2009 Not combined: the trials measured this differently, so the figures are reported as a spread rather than combined. | |
| Total harvested | 39,861 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.

* Measured differently in different trials. marketable yield, cull rate, and fruit weight varied between the trials above. AMSeed shows both figures rather than averaging them, because the difference between them is the finding: performance depends on the site, the season and the protocol, and a single blended number would hide exactly that.
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 2 trials we hold. That records where the plants stood, not where the variety belongs; no other system has been tested here.

Verticillium Wilt: Recorded separately for 1 of 3 named races, with the same response to each.
1 of these claims cite a publisher's whole output rather than one publication, and does not say where inside it the statement appears, so it cannot be looked up as cited. That is a gap in our records rather than a judgement on the claim, and it is counted and being worked down.
