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 NC State Fresh-Market Tomato Breeding Program (Mountain series). 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
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
| Measurement | Value | Context |
|---|---|---|
| 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. |
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.
later than 52% 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.
lighter than 60% of the 72 tomatoes we hold a figure for.
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 | 2.8-66 % | 2 observations from 2 trials, 2009 Not combined: the trials measured this differently, so the figures are reported as a spread rather than combined. | |
| Late Blight severity | 47.3-85 % | 2 observations from 2 trials, 2012-2013 | |
| Fruit weight | 9.0-11.1 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 | 16,706-17,061 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. | |
| Late Blight: disease progress (AUDPC) | 1,058.1 index | 1 observation from 1 trial, 2013 | |
| Total harvested | 49,095 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. 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.
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 4 trials we hold. That records where the plants stood, not where the variety belongs; no other system has been tested here.
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 |
| N | Root-Knot Nematode (Meloidogyne spp.) | resistant | Breeder declared |
V records that this variety has some resistance to this disease without naming which gene. The pathogen has 3 named races that different genes answer differently, so how much of it this covers is not established by the source.
FF records that this variety has some resistance to this disease without naming which gene. The pathogen has 3 named races that different genes answer differently, so how much of it this covers is not established by the source.
Verticillium Wilt: Recorded at disease level. This pathogen has 3 named races that varieties meet differently, and the source we cite does not distinguish them.
Fusarium Wilt of Tomato: Recorded at disease level. This pathogen has 3 named races that varieties meet differently, and the source we cite does not distinguish them.
Every resistance claim here cites 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.
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.
