How much, or in what ways, must one cultivar or crop breeding line vary from another in order to be considered different and distinct? Conversely, under which conditions might one be so similar – even if not exactly the same – as to be judged essentially as being the same as the other? Such questions are not just for philosophers. In a world in which ownership and control of crop varieties can define the limits of the availability of germplasm for use in breeding programs, as well as the potential for profits for commercial varieties, the question of derivatives becomes critical to the agricultural community in general and to plant breeders, legal experts and policy makers in particular. |
