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.

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.

Traits

Disease resistance

CodeDiseaseLevelBasis
- Early Blight (Alternaria linariae (A. solani)) tolerant Breeder declared
- Late Blight (Phytophthora infestans) tolerant Breeder declared

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.
