Try 'Multi-environment testing and genotype x environment interaction',
PN Fox, J Crossa and I Romagosa; in 'Statistical Methods for Plant
Variety Evaluation', Eds RA Kempton and PN Fox, 1997 Chapman and Hall.
ISBN 0 412 54750 3
This chapter also contains references which may be of use, and the whole
book is a good read anyway. It's still hardly a step by step guide
Since AMMI is a form of principal components analysis you will need
access to a computer programme to calculate the eigenvalues and vectors
of a matrices, or to a statistical package which will do the whole
analysis for you. I think GENSTAT has a procedure for this.
