RAPD markers for the identification of Populus species
Twenty five poplar clones, namely, 5 of Populus nigra, 5 of P. deltoides, 5 of P. alba, 5 of P. tremula, 1 of P. trichocarpa, 3 of P. x canescens and 1 of clone 'Platero' (P. tremula x P. alba 'Bolleana') were screened for random amplified polymorphic DNA (RAPD) markers in order to evaluate the use of RAPD analysis for distinguishing the cited species. One of the markers revealed different banding patterns between species and similar banding patterns for clones of the same species. For hybrids such as P. x canescens and 'Platero', the banding pattern was the same as either P. alba or P. tremula. On the other hand, for other hybrids analysed, such as P. x euroamericana I-214 and P. deltoides x P. alba 7/32 B, the banding pattern differed from both parents. The mentioned marker showed characteristic bands for every species, and in the particular case of P. alba three different groups could be distinguished.
