Mycelial compatibility of Valsa sordida isolates in Iran
Author(s):
Abstract:
In order to study of mycelial compatibility of Valsa sordida isolates on two culture media including potato dextrose agar and oat meal agar, 91 isolates that were collected from different provinces in 2004 and 2011 were used. In the prepared test, each isolate was paired with itself and with any of the other isolates. Dark barrage zone that shows incompatibility between two isolates, were observed seven days after parings. According to the results, thirty-eight single mycelial compatibility (MC) groups and eight multi-merge groups were identified on PDA culture medium and twenty-five single m-c groups and ten multi-merge groups on OMA culture medium were detected, showing the existence of high genetic diversity among the fungal isolates. In this study, no relationship between obtained MC groups on two culture media with geographic distribution and host plant origins of the fungal isolates was observed.
