Opinion on scientific definitions and technical scopes of words related to propagation and grafting of plants

Research output: Book/ReportReportProfessional

Abstract

As mentioned in the Introduction, vegetable seed companies have been confronted with the practice, that after production of scions from the seedlings of protected tomato varieties, the remaining stubs are not discarded but sold. In this way, two plants are produced from one seed: a scion for grafting onto a rootstock, and a stub that develops on its own roots into a new complete plant. Both are sold. The involved seed companies disagree with the nurserymen about the legality of this practice. This scientific / technical report provides independent opinions on the meaning and scope of words, such as grafting, production, reproduction, propagation, and multiplication, without giving a legal judgement. Further, this report underlines that it is technically feasible to trace the genetic identity of scions, stubs and rootstocks, also after grafting, and compare these with genetic identities of protected plant varieties. The aim of this report is to provide clarity about meanings and scopes of keywords, and in this way serve the involved parties to solve this issue in a legitimate way.
