    Description

    Yellow birch (Betula alleghaniensis Britt.) is an important hardwood species in the Lake States, northeastern United States, and eastern Canada. Since it produces valuable timber, the species is a logical candidate for genetic improvement. An understanding of the variation pattern in a species is, however, basic to any improvement program. In 1963 the Institute of Forest Genetics, Rhinelander, Wisconsin, initiated a study of natural variation in yellow birch. This paper describes variation in height growth and growth cessation in 2-year-old seedlings grown from the material collected for this study.
