Genetic variability and divergence among Italian populations of common ash (Fraxinus excelsior L.) [PDF]

open access: yesAnnals of Forest Science, 2007
The level of genetic variation throughout the Italian range of common ash (Fraxinus excelsior L.) was estimated using six microsatellite markers. High levels of allelic diversity was detected. The levels of expected heterozygosity for each of the populations ranged from 0.726 to 0.871, with an average of 0.798, and indicated that populations have a ...
