3. GEM Yield Trial Summary (Contd.)
Experiments: 31
Replicated at 4 to 8 locations
Plots: 12,500
Private cooperators’ portion: 69%
GEM portion: 31%

4. GEM Yield Trial Summary (Contd.)
There are 70 GEM topcrosses that out-performed the yield of check means
The range of CV’s for yield was from 8.8 to 16.6% (only 2 exps above 15%)
Yield trial data - high lodging data this year
Yields higher than expected for a stress year
