A field trial with plum cv. HoneySweet was established in 2003 in an experimental plot near Crop Research Institute in Prague-Ruzyně, Czech Republic, on the basis of a permission issued by the Ministry of the Environment of the Czech Republic. In addition to the evaluation of resistance of plum cv. HoneySweet to Plum pox virus, the field trial was used to evaluate gene flow of the inserted transgene. Sampling of blackthorn and myrobalan trees outside the field test site occurred at distances ranging from 544 m to 845 m from the test site and showed no gene flow, testing both plants and seeds collected from blackthorns and myrobalans. Similarly, seeds from plums cv. Jojo growing directly at the field test place did not show any presence of the transgene after seven years of evaluation.
