A field trial represents plots in the field where each plot has a globally unique plot_name, a sequential plot_number that is unique in the trial (e.g. 101, 102, 103 for three separate plots), and an accession_name representing the genotype being tested in that plot. Each plot can belong to different blocks (block_number) and reps (rep_number) depending on the experimental design you are using (e.g. complete block vs augmented design). Each plot can have a row_number and col_number indicating the relative position of the plot in the field.
If a specific accession is a check or control, you can indicate the plots that that accession is planted in as controls using is_a_control.
You can provide the specific seedlot_name planted in each plot, along with the number of seeds (num_seed_per_plot) and/or the weight (g) of seed (weight_gram_seed_per_plot) that were used.
A trial can represent a yield trial, a phenotyping trial, a crossing block, a greenhouse, a nursery, etc.
A plot can have many plants, which the database can track as separate entities, allowing you to record plant level observations and information.

If you go on to collect tissue samples for creating a 96 well plate for genotyping, when adding the genotyping trial (plate layout) to the database you can use plot names or plant names or tissue sample names from this field trial. By doing so, we can create linkage between this field trial and the genotyping plate.
If you go on to perform crosses on this field trial, each cross can be linked to specific female and male plots. When you upload these crosses we can then automatically link this field trial to the crossing trial in the database.
