Stephen — us grape growers have to sign similar agreements when we buy vines of some clonal varieties that have been developed by nurseries, universities, or government-supported programs such as INRA-ENTAV in France. We agree not to take cuttings to expand our own vineyards or provide them to others. We also pay royalties and fees. As with seeds, there are clonal selections of these grape varieties available that don’t carry these restrictions or fees. At this time there are no clones available of any variety that have been modified by modern targeted molecular technologies.
