The growers’ objective was to document the best green head lettuce for summer production across different farms throughout southern Ontario during the 2021 season.

In a Nutshell

  • Nevada was the top variety with respect to vigor, flavour, longest harvest, disease hardiness, and germination in this trial.
  • Muir was a runner-up to Nevada, but did have some germination issues and did not size up as well.
  • Concept and Encino were the growers’ least favorite varieties this year.
  • Overall, these results are consistent with the 2020 lettuce variety trial.
