Abstract
Genetic variation in seed samples of Cunninghamia lanceolata from two provenances of the western part of the People's Republic of China were studied. Genotypes of endosperm and corresponding embryo were scored simultaneously at ten enzyme gene loci. Intrapopulational variation is described by means of the actual and conditional heterozygosities and the genetic diversities. These are given separately for the pool of the female and the male gametic contributions to the embryos as well as the genotypes. The characterization of inter-populatioaal variation is based on a statistical comparison, on the genetic distances for alleles and genotypes, and on the measurement of population differentiation. The results clearly indicate considerable amounts of genetic variation within and between the studied provenances. Possible consequences for tree breeding are outlined briefly.
