2024 Products Tested Listings
Comprehensive listings of hybrids and varieties in the 2024 FIRST trials.
The 2024 Products Tested Directories are available below, and include full contact details for each of our sponsor and participant brands. See what new seed products our sponsors have entered in this year's tests. Each hybrid and variety that has been tested by FIRST in previous seasons is highlighted with a link to its individual Product Report.
Note that seed that has been entered by FIRST as a check (CK) in split maturity tests or as a grower comparison (GC) are designated with those abbreviations. FIRST includes these brands to strengthen results and is not compensated for the seed and field work for CK and GC products.

Testing Objectives and Procedures
FIRST provides a fair and objective platform under a uniform testing standard to compare seed productivity in a multitude of soil and growing conditions across 15 states. This year, over 2,000 seed products from over 70 seed companies were tested across 65 distinct growing regions. These replicated tests are conducted on over 300 farms, so that producers and ag professionals can better match seed performance with particular growing conditions. FIRST’s work relies on collaborations between cooperating farmers, sponsoring seed companies, FIRST Field Managers and publishing partners. FIRST is grateful for the opportunity to work with the agricultural community. The continuing goal of the program is to deliver of timely, unbiased comparisons of innovative seed genetics to improve yield and profitability for American farmers.

2024 Region and Location Details
FIRST trials are arranged in regions of several contiguous counties, with 5-6 plot locations for corn grain and 4 locations for soybeans and corn silage that are representative of the area. Each seed entered in the region is tested at all locations in order to provide 18-20 small plot observations in the entire region.
FIRST encourages you to use the Region Summary Reports published after all locations are harvested to evaluate the best performances across a range of locations and environments.
Region test plans with the number of entries and maturity range are listed below.
Tests are often split into different maturity ranges.
Maturity tests are abbreviated as:
- "u" for ultra-early maturity
- "a" for early-season
- "b" for late-season
- "l" for ultra-late maturity
