Abstract:
Anthracnose, caused by Colletotrichum gloeosporioides, is the major disease of almond in Israel. Pathogen attack of young fruit results in fruit rot and leaf wilting. Seventy isolates of C. gloeosporioides were obtained from affected almond fruits collected at 11 sites during 1991-2 and 1994. Chlorate-resistant nitrate-nonutilizing (nit) mutants were generated from each isolate and used in complementation (heterokaryon) tests. The formation of complementary stable heterokaryons between mutants from B different isolates showed that all the isolates belonged to a single vegetative compatibility group. Representative isolates of C. gloeosporioides from almond did not form heterokaryons with local isolates of Colletotrichum from anemone and avocado, indicating that the almond isolates constitute a distinct subspecific group within C. gloeosporioides.
