A mixed model analysis of variance for multi-environment variety trials

摘要

Of interest is the analysis of data resulting from a series of experiments repeated at several environments with the same set of plant varieties. Suppose that the experiments, multi-environment variety trials (as they are called), are all conducted in resolvable incomplete block designs. Adopting the randomization-derived mixed model obtained in Calinski et al. (Biometrics 61: 448-455, 2005), a suitable analysis of variance methodology is considered and relevant test procedures are examined. The proposed methods are illustrated by the analysis of results of a series of trials with rye varieties.
