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 Vegetable Varieties for Gardeners. 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
Park Seed's flagship hybrid since the 1980s, pairing large smooth fruit with heavy foliage cover that prevents the sunscald that spoils many big-fruited varieties.
Measurements
| Measurement | Value | Context |
|---|---|---|
| Days to maturity | 65-70 days | Consensus range across the cited sources, which include both independent references and commercial catalogs. |
| Fruit weight | 12-16 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.
earlier than 85% 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.
heavier than 60% of the 72 tomatoes we hold a figure for.
Traits
Disease resistance
| Code | Disease | Level | Basis |
|---|---|---|---|
| V | Verticillium Wilt (Verticillium dahliae) | resistant | Breeder declared |
| F | Fusarium Wilt of Tomato (Fusarium oxysporum f. sp. lycopersici) | resistant | Breeder declared |
| N | Root-Knot Nematode (Meloidogyne spp.) | resistant | Breeder declared |
| TMV | Tobacco Mosaic Virus (Tobamovirus tabaci / ToMV) | 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.
F 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.
