The 1985 manual by Jean Hanson on procedures for handling seed in genebanks has been extensively updated to include results of new research, technical advances in seed physiology, seed-storage behaviour and GM technology, as well as providing useful context in terms of the global framework of germplasm ownership and benefit sharing. The manual includes sections dealing with i) acquisition and registration, ii) seed cleaning, iii) seed moisture content determination and drying, iv) seed quality testing, v) packaging and storage, germplasm distribution and vi) monitoring and regeneration. Each section is packed with half-tone drawings, flowcharts and proforma tables to assist the reader in undertaking the various procedures. A series of appendices includes a useful list of specialist equipment for genebanks.

The emphasis is always on the practical, and the spiral-bound manual comes with wide margins for note writing. An accompanying CD in English and French on ‘Seed Handling in Genebanks’ is a triumph, comprising of 10 self-learning modules augmenting the major topics covered in the manual. These easy to follow and excellently illustrated modules start with learning objectives and end with a useful learning check. The CD bibliography impressively includes pdf files of related technical reviews and manuals as well as the text of the International Treaty. In my opinion this must-have manual and accompanying CD set a new benchmark for practical manuals of this type. The self-learning modules and associated resources will prove an essential reference for genbanks and for training new recruits and to complement courses.
