Abstract: Abstract Of interest is the analysis of results of a series of experiments conducted at several environments with the same set of plant varieties (called multi-environment variety trials). The most common practice is first to analyze individual trials and then to perform a kind of “synthesis” of the results obtained. This is considered as a two-stage approach to the analysis of the trial data. More recently a combined analysis of the raw plot data from all trials taken simultaneously has been advocated, as a one-stage approach to the analysis. The purpose of this article is to reconsider these two approaches with regard to the underlying models and the analyses based on them. The indicated differences between them are illustrated by a thorough analysis of a set of data from a series of trials with rye varieties. The required computations have been accomplished with the use of R.
