Abstract
One of the major goals of the study was to evaluate the reaction to chestnut blight of some local chestnut genotypes of Aydın Province of Turkey, chosen for possessing good yield and nut quality.
The other aim was to provide information whether Quercus species present in the province are alternative hosts of Cryphonectria parasitica (Murrill) Barr.
Among the C. parasitica population of Aydın Province two isolates K5-13 and N27-1, which were determined as the most and the least virulent isolates respectively, were used to assess the reactions of six chestnut genotypes.
According to the results of excised-stem inoculations all genotypes were considered susceptible, although differentiation concerning their degree of susceptibility was recorded among them.
As a matter of fact genotypes coded as N-3-4 (Işıklar) and N-20-2 were less susceptible than the others, while N-7-3 (Sarı Salman) was the most susceptible one.
No chestnut blight symptoms were detected on any of the oak species (Quercus cerris, Quercus coccifera, Quercus ilex) in nature.
However, in vitro inoculations with K5-13 isolate resulted in lesion development on all oak species; this indicates that they might be potential hosts for C. Parasitica.
