  1. Note:Please specify the GEM data manager if you have adjusted the yield at 15.5% moisture level.
  2. Additional Information needed for data analysis:
  1. Plot information (width x length) for calculating the yield
  2. Plant date & Harvest date
  3. Location (city, state)
  4. Number of seeds planted for calculating the percentage of plant standing

III. Explanation:

  1. EXPT = GEM experiment number that can be used to track the seeds and pedigrees
  2. Entry = Entry numbers
  3. Female Pedigree = Female pedigree if it's appropriate
  4. Tester = Male pedigree if it's appropriate
  5. Inventory No. = Inventory number that can be used to track the source of the seeds
  6. REP = Replications
  7. Plot = Field plot number
  8. WT = Plot weight of corn (lb/plot)
  9. Yield = The yield of the tested entry (Bushel/Acre) at 15.5% moisture level
  10. MOIST = Moisture of seeds at harvesting
  11. TWT = Test weight (lb/Bu)
  12. STD = Number of plants in the plot (actual number of plants)
  13. SLG = Number of stalk lodging
  14. RLG = Number of root lodging
  15. DEAR = Number of dropped ears
  16. PLTHT = Plant height in centimeter
  17. EARHT = Ear height in centimeter
  18. SG = Staying green
  19. Notes = Special notes
