Abstract

The influence of differences among ten black locust (Robinia pseudoacacia L.) clones and two years of research (2011 and 2012) in tolerance to Parectopa robiniella Clemens (Locust Digitate Leafminer) and Phyllonorycter robiniae Clemens (Robinia Leafminer) based on the intensity of leaf damage was examined. The intensity was evaluated by two characteristics: number of mines per leaf and percentage of damaged leaves. The results of these trials emphesise the significance of multiannual tolerance research, as well as the potential to select genotypes that are not considerably prefered by these of trails and also suggest that the genotypes could be selected that are not considerably preffered by these significant pests.
