Use of parallel coordinate plots in multi-response selection of interesting genotypes

Visualizing genotype-by-environment interaction in the case of several attributes, a situation that is often dealt with in plant breeding, is discussed in the paper. The parallel coordinate plot is proposed as an efficient tool for such visualization. Various applications of this type of graph are presented for across-environment and environment-wise plotting, thereby offering rich information about genotypes’ performance. It is shown how one can analyze the data and report the results by means of the parallel coordinate plots.
