Abstract: The current study sets out to analyse the concept of "essentially derived variety" (EDV) envisaged by the plant variety protection regime when new breeding techniques (NBTs) are employed in the development of new plant varieties. The use of NBTs to develop new plant varieties has grown rapidly over the last years because of their ease of use and their high efficiency. NBT varieties are mono-parental and retain most of the genome of the initial variety, thus most of its essential characteristics. The problem arises when the initial variety used as the source of genetic variation is a variety protected by a plant variety right. In this case, the question is whether the EDV concept should apply to the second variety obtained by NBTs and what can break the EDV chain. It must be noted that the EDV concept has revolutionised the plant variety protection system since it introduced the principle of "limited dependence" as an exception to the general independence principle governing this system. Therefore, as it is an exception, it should be interpreted rigorously.
