Abstract
RAPD (Random Amplified Polymorphic DNA) markers were used to identify 34 hybrid and 19 non-hybrid poplar (Populus) clones. The 35 consistent, distinct bands produced by seven 10-mer primers enabled the unambiguous identification of all except two of the clones tested. Similarity coefficients and principal co-ordinate analysis were used to assess the genetic relationships between clones. The results are discussed in the context of existing theories on the taxonomy of poplars.
