Illustration of the different stages of a typical evaluation process in cassava breeding. Plants from germinated seed (seedling plants) are grown in the field and used as the source of clonal planting material (left side). The first evaluation takes place in single row trials (SRT), followed by preliminary (PYT) and advanced (AYT) yield trials. The first multi-location evaluation is in the uniform yield trials (UYT), or sometimes earlier, in the AYTs. Size of plots in UYT has been slightly modified to illustrate the effect of different environments on the growth of cassava.
