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.

Origin & history

Another Baggett/OSU release, notable as one of the few open-pollinated tomatoes carrying the Ph-2 late blight resistance gene, bred for the blight-soaked Pacific Northwest.

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 68-70 days · ranked at its midpoint, 69
47.5 median 75 90

earlier than 79% 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.

MeasurementObservedEvidence behind itLevel
Late Blight severity 18.9-42.8 % 2 observations from 2 trials, 2012-2013
Late Blight: disease progress (AUDPC) 728.3 index 1 observation from 1 trial, 2013

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 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.
