The multiple approach promises more security of gains but is harder to manage. The optimal system will undoubtedly vary by species or species group. Since we and our inheritors all inhabit one planet with a common array of species to develop for greater or lesser use, the need for joint breed management programmes seems obvious. If we can afford joint programmes on gene pool conservation, we can surely afford joint programmes on gene pool evolution to manage them for diverse goals. The work of the Commonwealth Forestry Institute and the many bilateral efforts in breed development should be continued and supported.
