A simplified design for combined provenance and progeny testing

It is often desirable to combine the functions of provenance and progeny tests into one experiment testing the offspring of several different trees from each of many stands. A design is proposed whereby such an experiment may be simplified. The proposal is a variation of the compact-family design, with plots representing stands randomized within blocks, small sub-plots representing families within stands, and sub-plots systematically arranged within plots. The systematic arrangement is obtained by color coding when planting. That feature permits simplifications in the labeling, mapping and record keeping procedures without a sacrifice in quality of data. With the proposed design, a combined provenance-progeny test can be conducted almost as simply as an ordinary provenance test.
