Procedures and Designs Useful for Screening Material in Selection and Allocation, with a Bibliography

This paper represents a brief review of results on screening. The references listed in the paper were selected to illustrate diversity of topics related to screening procedures with particular attention being paid to the results for plant and animal breeding screening programs and from truncation, fragmentation, and censoring of samples. Also, the large number of journals involved should be noted. In this form it is hoped that researchers involved in screening various drugs, pesticides, fumigants, herbicides, etc. (and also with students, enlistees, missiles, etc.) will become acquainted with the topics and some of the literature on screening in breeding fields, and vice versa. With this in mind, the similarities in biochemical and breeding programs were stressed. In particular, the developmental phase, the evaluation phase, and the production or maintenance phase are common to both fields. Many of the statistical results obtained in one field are applicable to the other. No discussion is given concerning unsolved statistical problems related to screening. This subject is discussed in papers listed at the end of the paper. Some comments are given on experimental designs useful for multistage screening experiments. Particular reference is made to the class of designs known as augmented designs.
