We collected eight field data sets of potatoes farms in five years (2004~2008) from Taiwan Seed Improvement and Propagation Station. Besides, generalized linear models were employed to estimate the proportion of the individual plant infected. By mean square error as criteria. optimal group sizes were changed from 20 to 40 plants per group so that the cost was reduced and the testing process was improved efficiently. Not only can the group-testing design advance the accuracy of testing, but it can reach to the purpose of optimization.
