  5. GEM-Ames Data on Website • 70 Corn images for GEM-Ames released lines (in PDF format): • Observation data of breeding crosses: year 2009 to 2012 • Characterization data: year 2006 to 2012 • Disease data from year 2007 to 2012 • Lab NIR data and DSC data • GEM yield trial data: year 1999 to 2013 Germplasm Enhancement of Maize

  6. 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

  7. GEM Disease Evaluation Data Germplasm Enhancement of Maize

  8. GEM-Ames trial summary - 2013 • Experiments: 40 • Replicated at 4 to 8 locations • Plots: over 10,000 • The number of total reps lost due to weather: 9 (4.0%) • The number of experiments that have 2 or more reps lost: 3 (1.3%) • No experiment was lost because of weather Germplasm Enhancement of Maize

  9. GEM-Ames trial summary - 2013 Germplasm Enhancement of Maize

  10. GEM-Ames trial summary - 2013 • There are 261 top crosses that out-performed the mean yield of 5 checks (14.2% of 1839 entries of the top crosses) • Of these 261 GEM top crosses, 186 were from the first year tests and 75 from the second year tests • The range of CV’s for yield is from 8.3 to 18.2% (11.1-23.1% last year ) and the mean of the CV’s is 12.4% (last year 15.2%) Germplasm Enhancement of Maize
