Improving quality control procedures for seed-borne pathogens by testing sub-samples of seeds

Ridout, M.S. (Horticulture Research International, Kent (United Kingdom)) | Roberts, S.J.
Quality control procedures for seed-borne pathogens may involve testing a single sample of seeds for the presence of the pathogen, but the probability of rejecting seed-lots with acceptable infection levels can be high. If multiple sub-samples are tested and the seed-lot is rejected when any of the sub-samples gives a positive result, then the probability of inadvertantly rejecting acceptable seed-lots is unchanged. However, this probability can be reduced, without reducing the probability of rejecting unacceptable seed-lots, by requiring more than one of the sub-samples to give a positive result before rejecting the seed-lot. We present the underlying statistical theory behind this result and discuss the implications for seed testing procedures
