Disease Resistance in Coffee Berries-Comparative Resistance in Single Trees

Abstract

The fungus Colletotrichum coffeanum Noack (Glomerella cingulata) (Stonem, Spauld and Schrenk) can cause a destructive disease of coffee berries (Macdonald, 1926; Nutman and Roberts, 1960) to which the best long-term approach is breeding for resistance. There have been early reports of studies on resistance to Coffee Berry Disease (Nutman and Roberts 1960, Firman 1964) which describe inoculation and other experiments on detached berries of named varieties of coffee.
