Helmut Gangl works also on the breeding and cloning of vines. A clone is a vegetative descendant of a source plant. Cloning exclusively uses the natural genetic resources of the plant which are acquired through directed selection. In addition, the mother plants are always maintained under phytosanitary controlled conditions. The transfer of the inheritance material in this case is only carried out through vegetative reproduction (refinement) within a clonal line. The grafted vine plants so-produced come to preliminary-stage and basis facilities and are also maintained under controlled growth conditions until they are certified. Very important is the performance of the vine clones in the respective ecosystem. That is why we set a high value on regional circumstances. The following vine clones by Helmut Gangl are officially recognised and are available on the vine market: Zweigelt: Klon GU3 St. Laurent: Klon GUL2 Klon GU4 Klon GU5 Klon GU6 Klon GU7 Klon GU8 Klon GU9 Klon GUL3 Klon GUL4 Klon GUL6 Klon GUL9 Klon GUL10 Helmut Gangl is currently working on the cloning of the following vines from different viniculture areas: Bouvier Grüner Veltliner Riesling Chardonnay Blaufränkisch Cabernet Sauvignon Merlot
