Thanks Anthony Vander Horst. I can run ANOVA but need to show like bar diagram in the same place of 220 genotypes with their treatment comparison. Now I would like to know is there any other option that can show whole data in one figure?
in genetics heatmaps are often used for your purpose. Heatmaps display a lot of information, f.e. hundreds of means, within one coloured diagram and can be very instructive - at least at a descriptive level. Heatmaps are easily produced with R and other statistical programs (or even Excel).
