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.
Evaluation of Late Blight Resistant Tomato Varieties, 2013
2013 · New York · full season · published as "Iron Lady"
| Measurement | Result | Method |
|---|---|---|
| Late Blight severity | 1.6 % | Visual severity rating under natural infection |
| Late Blight: disease progress (AUDPC) | 125.2 index | Area under the disease progress curve |
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.
