GEM Disease Evaluation Data
The method of disease evaluation is upon the collector1 ~ 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

GEM-Ames trial summary - 2012
There are 242 top crosses that out-performed the mean yield of 5 checks (10.5% of 2311 entries of the top crosses)
Of these 242 GEM top crosses, 189 were from the first year tests and 53 from the second year tests
The range of CV’s for yield was from 11.1 to 23.1% (9.0-21.1% last year ) and the mean of the CV’s is 15.2% (last year 13.5%)
