The random amplified polymorphic DNA (RAPD) technique offers a useful tool to detect DNA polymorphisms. It can also be used to distinguish different clones and cultivars. We have developed a comprehensive RAPD-based procedure for the routine molecular typing of various plants. Here we report the application of this technique for the correct identification of six hazelnut cultivars (Corylus avellana) widespread in the Campania region (south Italy). The analysed hazelnut cultivars were successfully distinguished by their RAPD fingerprints using the DNA primers U2, U3, U4, UI I and U14. However, in each cultivar we observed very low genetic heterogeneity among the clonal variants. Since this technique is among the simplest and easiest: methods used to Fingerprint DNA, it could be easily transferred to less sophisticated laboratory infrastructures (e.g. outstations of crop regulatory agencies).

Abstract
The random amplified polymorphic DNA (RAPD) technique offers a useful tool to detect DNA polymorphisms. It can also be used to distinguish different clones and cultivars. We have developed a comprehensive RAPD-based procedure for the routine molecular typing of various plants. Here we report the application of this technique for the correct identification of six hazelnut cultivars (Corylus avellana) widespread in the Campania region (south Italy). The analysed hazelnut cultivars were successfully distinguished by their RAPD fingerprints using the DNA primers U2, U3, U4, UI I and U14. However, in each cultivar we observed very low genetic heterogeneity among the clonal variants. Since this technique is among the simplest and easiest: methods used to Fingerprint DNA, it could be easily transferred to less sophisticated laboratory infrastructures (e.g. outstations of crop regulatory agencies).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
