Similarity among entries

From Biplot Tools, click Relation among Entries, and the vectors of the entries will appear on the biplot. If the biplot was not in the entry-focused singular value partitioning (i.e., SVP =1), this method will be automatically applied, which may change the shape of the biplot.

Interpretations:

• Entries with longer vectors are more responsive to the testers, i.e., they have either large main effect (G, i.e., greater or smaller than the average) or large interaction with the testers (GE) (e.g. entries 3 and 7); those with short vectors are less responsive (entries 1 and 2). Entries located at the biplot origin performed intemediately with regard to all testers.
• Entries are similar in both main effect and interaction with the environments if they are placed closely in the biplot (e.g. entries 2 and 5).
