Part of the Forestry Sciences book series (FOSC, volume 42)


Biochemical markers are ideally suited for addressing questions concerning genetic or parental identity. For production seed orchards, such questions are common as a consequence of the uncertainty of paternity in non-controlled cross situations. During the last decade, electrophoretic procedures have been used extensively to investigate issues such as:
  • clonal identification,

  • pollen contamination levels,

  • mating systems,

  • supplemental mass pollination (SMP) verification,

  • patterns of gene flow, and

  • levels of pollen competition.

A number of patterns have emerged from this work. Most notable, contamination rates are disturbingly high, clonal phenology and pollen application methodology influence SMP success, and phenology and proximity are important in determining paternal success. Results are discussed with reference to orchard management prescriptions.
