Data product containing 20-year tree heights, diameters, and genetic variation for "Scots pine in eastern Nebraska: A provenance study"

Seedling progenies of 36 rangewide provenances of Scots Pine (Pinus sylvetris) were established in a field test at Horning State Farm experimental area near Plattsmouth, Nebraska in April of 1962. Tree heights were measured at the end of each growing season from 1963 through 1969, and again in 1971. Tree height and diameter at breast height were both measured at the end of the growing season in 1976, 1978, 1979, and 1981.
The objective of this study was to find and develop better adapted genetic tree materials for use in all kinds of plantings, environmental and commericial throughout Nebraska and the Central Plains. The study of different species provided basic materials of known origin for evaluation of adaptability for study of genetic variation, selection, propogation, and breeding resistance to disease and insect pests.
