Variety description

10 August 2026

The variety was bred in Cambridge by crossing Little Joss and Victor varieties. By modern standards, the plant is tall, as it does not contain the Rht-B1 or Rht-D1 semi-dwarfing alleles characteristic of Green Revolution-era varieties.

In comparative scientific studies, the variety is treated as a historical specimen, demonstrating specific root system development parameters that differ from modern commercial hybrids. Information regarding its yield and baking quality is absent in the literature.
