Abstract

Necrosis of needles and shoots caused by various damaging agents, have emerged about fifteen or twenty years ago in the Hungarian Austrian pine stands. Damages caused mainly Sphaeropsis sapinea Dyko & Sutton, Mycosphaerella pini E. Rostrup (its anamorph Dothistroma septospora /Dorog./ Morlet), and Sclerophoma pithyophila (Corda) Höhn, and Cenangium ferruginosum Fr. ex Fr. Appearance and rapid spread of the fungi may surely be attributable to the anomalies in weather conditions. Since, the prevailing conditions, according to the long term predictions, have a fair chance of becoming permanent, it seems to be rational to select resistant or less susceptible species in producing propagation material of Austrian pine in the future. This brought up the investigation on the susceptibility of those clones, which are considered as basis for the elite propagation material of Austrian pine, to individual damaging agents. The investigations were carried on clone bank of Kisunyom. The results showed the susceptibility to the damaging agents considerable differences prevailed among the clone-groups, so it has been confirmed that in the process of genetic improvement when individuals are selected for cultivation, their susceptibility to the damaging agents should also be considered.
