Diversity--The Only Assurance Against Genetic Vulnerability to Disease in Major Crops

I am honored to address this distinguished group interested in and dedicated to the improvement of forest trees. There is precedent for a small grain pathologist's addressing tree breeders, as at least two forestry symposia, in 1964 and 19 69 , included papers by small grain workers. The implication was that small grain breeders and pathologists had shown the way, and that tree scientists should learn from successes with small grains. The successes have been many but, unfortunately, there also have been failures with small grains and other intensively bred crops. The message I hope to leave tonight is that breeders and pathologists of both field crops and trees can learn from the failures as well as the successes, and that both can profit from emulating or maintaining natural ecosystems such as most forests represent.
