Teosinte lines were selected based upon seed availability and previous research performed by other groups (Flint-Garcia et al., 2009). Teosinte lines were from the Guerrero, Mexico area, approximately 1100 km apart, and had varying seed characteristics. Teosinte lines were grown during the 2014 growing seasons at the South Dakota State University Aurora Research Farm. Soil series was a Brandt silty clay loam (fine-silty, mixed, super-active, frigid Calcic Hapldolls). Additional information regarding the experimental location is available in Clay et al. (2009). Lines were planted May 30, 2014 in an amended four replication split-plot design, with teosinte line being the main treatment, and weedy or non-weedy being the sub-treatment. Plots were fertilized with 140 kg N/hectare with urea treated with urease inhibitor the 1st week of June. Individual treatment plots consisted of a 3.6-m2 area, with 4 seeds (2014) planted in a 3-m x 3-m plot at an equilateral distance from each other and from plot borders. A naturally abundant weed population was allowed to grow unchecked in weedy plots, whereas weed free plots were maintained weed free by hand hoeing and weeding during the growing season.
