  3. GEM-Ames Data on Website • Corn images for GEM-Ames released lines (in PDF format): • 64 images as a total (from yr 05 to 11) • Disease data from year 2007 to 2011 • Data of observations of breeding crosses (from year 2009 to 2011) • More data will be included from international cooperators • Characterization data (from yr 2006 to 2011) • Lab NIR data and DSC data Germplasm Enhancement of Maize

  4. Usage of GEM-Ames website The data page on GEM website Germplasm Enhancement of Maize

  5. GEM-Ames trial summary - 2011 • Experiments: 51 • Replicated at 5 to 8 locations • Plots: 17,000 • The number of complete experiments lost: 1 (2.0%) • The number of experiments that have 2 or more reps lost: 8 (15.7%) • The number of total reps lost due to weather: 41 (14.3%) Germplasm Enhancement of Maize

  6. GEM-Ames trial summary - 2011 • There are 251 top crosses that out-performed the mean yield of 5 checks (8.3% of 3028 entries of the top crosses) • Of these 251 GEM top crosses, 226 were from the first year tests and 25 from the second year tests • The range of CV’s for yield was from 9.0 to 21.1% (9.3-17.2% last year ) and the mean of the CV’s is 13.5% (last year 12.8%) Germplasm Enhancement of Maize
