2021 SeedLinked Collaborative Trial Results

The SeedLinked Team
5 minute read

In 2021, we organized and hosted three collaborative trials for three different crops – indeterminate paste tomatoes, fresh market green bush beans, and jalapeños – with the help of an awesome group of gardeners and farmers across North America. 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.

Before we go any further, we want to thank each of the growers who dedicated growing space and time to growing and rating the varieties on SeedLinked. We couldn’t do this work without your support and expertise. Thank you!

Trial Methods

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 trial. Each of these trials was a triadic 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.

2021 SeedLinked Trial Participant Locations

During the 2021 growing season, trial participants were asked to grow the varieties provided to them and log in to SeedLinked on the web and/or mobile app and input their 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.

Trial Results

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 so that you have access to filtering 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 about all the ways you can filter and view trial results.
