Height variation in a five-year-old yellow-poplar provenance/progeny test in Illinois
Yellow-poplar height growth can be increased up to 10 percent by selecting the proper seed source; in southern Illinois this seed source is southwest Kentucky or Tennessee. Individual-tree selection in the progeny test will increase height growth from 3 to 7 percent, depending on whether applied with or without provenance selection. Stability analyses of height data indicated that selection of half-sib families on the basis of mean height alone should probably be avoided and that the seedling seed orchard approach would not be effective for improving yellow-poplar.
