This chapter addresses twelve frequently asked questions on the use of biplots in data analysis. The questions include: what do I need to do before conducting biplot analysis?; is the biplot adequate in displaying the patterns of the two-way table?; what if the biplot does not adequately display the data?; and what if the dataset has missing values?. The chapter also discusses eight frequently seen mistakes in interpreting a biplot and provides corrections for them. The mistakes include: the GGE biplot displays the correlations between genotypes; biplots not drawn to scale; GGL biplot based on a genotype-by-location two-way table averaged across years; and GE biplot can be interpreted similarly as the GGE biplot.Read More
