A new technique for analyzing the genetic structure of trees is available. Enzymes from germinating embryos were resolved by starch gel electrophoresis. Three polymorphic loci were identified in related families of knobcone pine (Pinus attenuata Lemm.). Progenies in 16 control-pollinated families from 12 parent trees were tested. Isozymes for one alcohol dehydrogenase (ADH) locus and for two leucine aminopeptidase (LAP) loci segregated according to the laws of diploid inheritance, with two alleles per locus. Segregation in the progeny of a parent tree heterozygous for one ADH and one LAP locus showed these two loci are unlinked. Forest Sci. 17:190-194.
