Genotype by environment interaction in variety trials

Data sets from official variety trials carried out in Croatia from 1992 to 1998 were analyzed using EM-AMMI models. Amount of missing cells in all four data sets (winter wheat, spring barley, winter barley, spring oats) was more than 60%. Only for spring oats data sets cross validation procedure detected AMMI1 as the best model, while for remaining three data sets detected best models were either too complex or too noisy.
