Corn Population Catalog

The USDA Organic Research and Extension Initiative project “Strengthening Public Corn Breeding to Ensure that Organic Farmers Have Access to Elite Cultivars” included a multi-year evaluation of open-pollinated corn varieties and populations at organic locations. Varieties and populations from all of the participating institutions were evaluated at locations in Arizona, Illinois, Iowa, New Mexico, New York, and Wisconsin (site locations indicated on map). Lajas, Puerto Rico was the organic, winter nursery location for the project.

They were included in yield trials planted in 1/500 acre plots (two 17.5’-long rows at 30” row spacing) with two replications at each location. Each plot was harvested and grain weight and grain moisture percentage were measured. Grain yields were calculated in bushels/acre at 15.5% moisture. At harvest time, the number of stalks broken (or lodged) below the ear was counted. This number was expressed as a proportion of the total number of plants in the plot (percent stalk lodging). Plants leaning over from the base at more than a 45˚ angle were counted as root lodged, and expressed as a proportion of the total number of plants in the plot (percent root lodging).

Not all populations were evaluated in all locations or in all years. Poor performing varieties or populations were dropped out, and newly developed or identified ones were added as time went on. Populations that were inappropriate in adaptation at some sites were evaluated only where they might reasonably be adapted. Different sites and years had dramatically different yields. For all of these reasons, be mindful when reading the summary yield data as it is reported in bushels per acre across all sites and years.

Yield, grain moisture, and lodging data is summarized below for all locations and years. Population descriptions, who to contact for more information about these populations, site descriptions, and individual location data are provided on linked pages.
