Types of Basic Material

Basic Material is material from which reproductive material may be collected or produced and which is in one of the types defined below:

  • Seed sources (RP)
    This covers all material from a single tree to any collection of trees within a region of provenance or seed zone.


  • Stands (ST)
    Specifically identified areas or groups of trees with identified boundaries


  • Seed orchards  (SO)
    Plantations based on individuals which are represented by propagules (vegetative or seedling) of known individuals derived from selection and breeding work.


  • Parents of families (PF)
    One or a number of individual parent trees used to produce seed which could be used for the direct production of planting stock or be the basis of subsequent multiplication by vegetative propagation.


  • Clones (CL)
    All the vegetative propagules used as planting stock which were originally derived from one individual tree.


  • Clonal mixtures (CM)
    A mixture of clones with known composition

The FRM collected from this Basic Material could therefore be cones, fruits, seeds, all parts of plants obtained by vegetative propagation, including embryos and plants produced from any of these or parts of plants. Normally, only FRM that comes from registered basic material can be marketed.
