GEM Disease Evaluation Data
The method of disease evaluation is upon the collector1 ~ 5 scale1 ~ 9 scale1 ~ 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 - 2013
There are 261 top crosses that out-performed the mean yield of 5 checks (14.2% of 1839 entries of the top crosses)Of these 261 GEM top crosses, 186 were from the first year tests and 75 from the second year testsThe range of CV’s for yield is from 8.3 to 18.2% (11.1-23.1% last year ) and the mean of the CV’s is 12.4% (last year 15.2%)
