Troubleshooting
Problem
Solution
Large variation of morphology within a plot.
Check seed origin – i.e., confirm the seed is not mixed with
other genotypes.
Ensure that the sowing and crop husbandry is uniform across
each plot (e.g., even sowing depth for all rows).
Observe a larger area of plot, or take more samples per plot.
Separate into groups within a plot (and ensure to make a
comment on the field form; e.g., values for short/tall).
Large variation in data within a plot.
