Origin & history
An early determinate market hybrid popular across the South for combining early maturity with heat-set ability and firm, shippable fruit.

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.

Yield and Income of Fall Staked Tomato Cultivars in Eastern Kentucky
2009 · Quicksand, Kentucky · fall · published as "Primo Red"
| Measurement | Result | Method |
|---|---|---|
| Marketable yield * | 20,036 lb/ac a | Diameter-class grading of breaker-stage fruit, Per-acre yield extrapolated from small research plots |
| Cull rate * | 11.4 % a | Diameter-class grading of breaker-stage fruit |
| Fruit weight * | 8.2 oz cde | Mean fruit weight from plot counts and weights |
* 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.
Traits
Disease resistance
| Code | Disease | Level | Basis |
|---|---|---|---|
| V | Verticillium Wilt (Verticillium dahliae) | resistant | Breeder declared |
| FF | Fusarium Wilt of Tomato (Fusarium oxysporum f. sp. lycopersici) | resistant | Breeder declared |
| TSWV | Tomato Spotted Wilt Virus (Orthotospovirus tomatomaculae) | resistant | Breeder declared |
Breeder declared means the resistance was stated by whoever breeds or sells the seed. That is not a reason to disbelieve it, and for most resistance genes it is the only evidence that exists: the breeder screens the line and publishes the result in their catalog, and no independent party re-tests it. We label it rather than quietly presenting it as though someone had checked.
