Abstract:
Phellinus torulosus (Pers.) Bourd. et Galz. is the causal agent of white rot that infects especially the roots and the collar of old trees and shrubs of many species. The random amplified polymorphic DNA (RAPD) technique using polymerase chain reaction (PCR) was used to explore the genetic variability in 138 P. torulosus isolates from 139 oak woods of Apulia and Basilicata. The use of 16 random primers yielded 150 polymorphic fragments. The dendrograms generated by analysing RAPD data did not show correlations between the clusters and other characters such as morphotypes, host species, and geographic origin.
