Origin & history

The east-coast market grower's box tomato from NC State's Mountain series: big uniform fruit engineered for flavor plus shipping, with N added to the classic V-F package.

Measurements

MeasurementValueContext
Days to maturity 75-78 days Consensus range across the cited sources, which include both independent references and commercial catalogs.
Fruit weight 8-12 oz Typical range for the cultivar, as a consensus across the cited sources. Not a measured mean from any single crop: fruit weight varies with season, spacing and where on the plant the fruit set.

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.

* Measured differently in different trials. disease severity, 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

CodeDiseaseLevelBasis
V Verticillium Wilt (Verticillium dahliae) resistant Breeder declared
FF Fusarium Wilt of Tomato (Fusarium oxysporum f. sp. lycopersici) resistant Breeder declared
N Root-Knot Nematode (Meloidogyne spp.) 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.
