Summary:
In plant breeding trials, during the early stages of the improvement process, it is not possible to use an experimental design that satisfies the requirement of replicating all the treatments because of the large number of genotypes involved, the small amount of seed and the low availabi-lity of resources. Hence, the unreplicated designs are used for early generation testing when hundreds or even thousands new genotypes need evaluation in the same trial using a limited amount of seed that is enough for one replicate only. To control the real or potential heterogeneity of experimental units, control (check) plots are arranged in the trial.
