GEM-Ames trial summary - 2007

There are 170 (88 last year) GEM topcrosses that out-performed the yield of check means (out of 2330 entries of topcrosses)

26 topcrosses out-performed the top check

The range of CV’s for yield was from 7.6 to 19.2% (only 1 expt above 15.5%)

Yield trial data - high lodging data this year (good selection for lodging resistant?)
