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 Burpee catalog. 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

Burpee's ultra-early, named for its promise: ripe four-ounce fruit by Independence Day in most of the country.

Measurements

MeasurementValueContext
Days to maturity 49-55 days Consensus range across the cited commercial catalogs; no independent source documents it yet.
Fruit weight 3-4 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.

Days to maturity 49-55 days · ranked at its midpoint, 52
47.5 median 75 90

earlier than 99% 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.

Fruit weight 3-4 oz · ranked at its midpoint, 3.5
2.5 median 12.0 32.0

lighter than 97% of the 72 tomatoes we hold a figure for.

Traits

Disease resistance

No documented disease resistance, typical of heirlooms and older open-pollinated varieties. See tomato diseases for the cultural playbook that fills the gap.
