Wright, B. D. (1998). Intellectual and Farmers' Rights. In R. Evenson, D. Gollin & V. Santaniello (Eds.), Agricultural Values of Plant Genetic Resources (p. 219-232). Wallingford: FAO/CEIS/CABI Publishing.

In this book chapter, B. D. Wright highlights the paradox of the high total value of agricultural germplasm and the current low demand of plant breeders for such material due to their own well-stocked gene banks and the narrow genetic bases of their crop varieties.

Therefore any attempt to seek to earn rents on access to germplasm seems likely to fail. Against this backdrop, the author concludes that care must be taken that the exchange of seeds is not too severely hampered by taxes, fees or individualized prior approval requirements.
