Collabrotive trial results are in! In 2021, we organized three trials for three different crops – indeterminate paste tomatoes, fresh market green bush beans, and jalapeño peppers. The goal of each trial was to grow well-known varieties side-by-side with newly released hybrid and open-pollinated varieties and freely share the results on our Seed Search and in this blog with growers, seed companies, and anyone else who is interested.
In January 2021, we canvased United States seed company offerings and selected varieties in each crop/market class that were standard open-pollinated and hybrid varieties. Additionally, we looked for newly bred and/or released open-pollinated and hybrid varieties to grow alongside them for comparison in these trials.
In February 2021, we invited farmers and gardeners across the United States to join our three trials via the SeedLinked platform by reaching out to those who have successfully been part of trials in the past as well as through an open link on our website. We had 92 growers join the indeterminate paste tomato trial, 113 growers join the fresh market green bush bean trial, and 73 growers join the jalapeño pepper trial. Each of these trials was a sub-set trial, where each participant was randomly assigned three varieties of a larger set to grow side-by-side and rate them. Also in this month, we mailed seeds and planting stakes to participants and made the trial active on the SeedLinked platform.
During the 2021 growing season, trial participants were asked to grow the varieties provided to them. The participants logged in to SeedLinked on the web and/or mobile app and input the following data: planting, transplanting, first harvest, and last harvest dates, rate a variety of traits on a scale of 1 to 5 stars, provide general and trait-based written comments, and share photos of the varieties growing.
Once the trials were closed for entering data in December 2021, results were automatically calculated by the SeedLinked platform and shared with participants. You can view links to interactive trial results below. We highly recommend logging into your existing SeedLinked account or creating an account when viewing the results. This gives you the opportunity to filter results by hardiness zone to zero in on varieties that performed well in your location. Additionally, we recommend checking out our blog ‘Digging into SeedLinked Trial Results‘ to learn how to filter and view trial results.

Thank you to all of the gardeners and farmers who participated in SeedLinked trials in 2021. With your help, we are creating more open-source data for how vegetable varieties perform across the United States. Additionally, we would like to thank all the seed companies that shared seeds with us for the trials. Thanks for being open to having your varieties tested by a wider audience of growers around the United States.
