About this book
Plant breeders are dependent upon the availability of a large pool of diverse genetic material represented by local races and wild relatives. Without the ability to draw from a diverse genetic reservoir, further improvement of crops may not be possible. These guidelines have been produced by the IPGRI, together with the FAO, IUCN and UNEP, and they are designed to be a comprehensive reference work for both new and experienced collectors and for those with a general interest in plant genetics, breeding and biodiversity.
