GEM-Ames Data on Website Germplasm Enhancement of Maize Corn images for GEM-Ames released lines (in PDF format): 70 images as a total (from yr 05 to 12) Observation data of breeding crosses: year 2009 to 2011 Characterization data: year 2006 to 2011 Disease data from year 2007 to 2011 Lab NIR data and DSC data

GEM Disease Evaluation Data The method of disease evaluation is upon the collector 1 ~ 5 scale 1 ~ 9 scale 1 ~ 7 scale It was proposed to use one GEM rating scale to facilitate comparisons and has been approved by the TSG in September 2012. GEM disease evaluation scale: 1 ~ 9 (1 = resistant and 9 = susceptible) All the disease evaluation data contain both the original scale and GEM scale Germplasm Enhancement of Maize

GEM-Ames trial summary - 2012 Germplasm Enhancement of Maize Experiments: 41 Replicated at 5 to 8 locations Plots: 13,000 The number of complete experiments lost: 1 (2.4%) The number of experiments that have 2 or more reps lost: 4 (9.8%) The number of total reps lost due to weather: 29 (12.3%)

GEM-Ames trial summary - 2012 There are 242 top crosses that out-performed the mean yield of 5 checks (10.5% of 2311 entries of the top crosses) Of these 242 GEM top crosses, 189 were from the first year tests and 53 from the second year tests The range of CV’s for yield was from 11.1 to 23.1% (9.0-21.1% last year ) and the mean of the CV’s is 15.2% (last year 13.5%) Germplasm Enhancement of Maize
