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
An early determinate in the Mountain series bred for spring plantings, producing smooth crack-free fruit before the summer heat shuts down 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.
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 | 69 % | 1 observation from 1 trial, 2009 | |
| Fruit weight | 10.4 oz | 1 observation from 1 trial, 2009 | |
| Marketable yield | 13,701 lb/ac | 1 observation from 1 trial, 2009 | |
| Total harvested | 43,185 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.

| Measurement | Result | Method |
|---|---|---|
| Marketable yield | 13,701 lb/ac cdefg | USDA U.S. No. 1 grade and size classification, Per-acre yield extrapolated from small research plots |
| Total harvested | 43,185 lb/ac bcde | Per-acre yield extrapolated from small research plots |
| Cull rate | 69 % abcd | USDA U.S. No. 1 grade and size classification |
| Fruit weight | 10.4 oz cdef | Mean fruit weight from the marketable lot |
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.
Traits
Disease resistance
| Code | Disease | Level | Basis |
|---|---|---|---|
| V | Verticillium Wilt (Verticillium dahliae) | resistant | Independently observed |
| FF | Fusarium Wilt of Tomato (Fusarium oxysporum f. sp. lycopersici) | resistant | Independently observed |
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.
