Enzyme Electrophoresis-Application of Molecular Biology to Forest Genetics Research

Despite the wealth of information concerning quantitative variation in forest trees, little information is available to answer a fundamental question: What is the relationship between the percentage of loci heterozygous in an individual tree and the growth performance and geographic origin of that tree? On a provenance basis, this question can be expanded to include consideration of polymorphism at single loci. In other words, in a population of forest trees, how many different alleles (isoalleles) occupy a single locus? These questions are not new to biology (Mayr, 1963). A molecular approach designed to provide answers to these questions is new (Hubby and Lewontin, 1966) and deserves the attention of forest tree improvement researchers.
