Evaluation of resistance to anthracnose (Marssonina juglandis) among diverse Iranian clones of walnut (Juglans regia L.)



Evaluation of resistance to anthracnose (Marssonina juglandis) among diverse Iranian clones of walnut (Juglans regia L.)



Journal of Food Agriculture and Environment 8(2): 375-378



Recently, a majority of walnut (Juglans regia L.) trees had been identified with necrosis on leaves and branches in the northwest of Iran, due to infection of black spot (anthracnose). The disease was associated with premature phylloptosis and severing when it was rainy and it caused major defoliation in infected trees. Burning infected plant materials relatively reduced severity of disease, but this was not an effective method to control it. An experiment was conducted to identify the most resistant cultivar to disease in the northwest of Iran, during 2005 to 2007. Result of inoculation of different walnut clones by spore suspension (10(5)) in glasshouse showed that the Marssonina juglandis fungus was causal agent and perfect stage was Gnomonia leptostyla. The provenance of Ghazvin was demonstrated to be the source of highest proportion of resistant plants for cv. Alamoty, while Zeiabadi showed intermediate proportion of resistant plant. The different environmental conditions, related to walnut orchard site, influenced the whole disease intensity but not the specific behavior of each single provenance towards the disease. Alamoty cultivar did not show any anthracnose symptoms in any garden at natural condition. The information obtained on clone resistant to anthracnose could be very valuable as basis for the purposes of breeding resources and the production of improved material to be used in new walnut orchards.
