Classification of Maize Environments Using Crop Simulation and Geographic Information Systems

The effectiveness of a cultivar evaluation system largely depends on the genetic correlation between genotype performance in multienvironment trials (MET) and in the target population of environments (TPE). Previous classifications of maize ( Zea mays L.) environments on the basis of climate and soil did not quantify their impact on the genetic correlations among environments. Consequently, plant breeders have favored classifications based on...
