Abstract EN
Orobanche cumana is a holoparasitic plant naturally distributed from central Asia to south-eastern Europe, where it parasitizes wild Asteraceae species.
It is also an important parasitic weed of sunflower crops.
The objective of this research was to investigate genetic diversity, population structure, and virulence on sunflower of O.
cumana populations parasitizing wild plants in eastern Bulgaria.
Fresh tissue of eight O.
cumana populations and mature seeds of four of them were collected in situ on wild hosts.
Genetic diversity and population structure were studied with SSR markers and compared to weedy populations.
Two main gene pools were identified in Bulgarian populations, with most of the populations having intermediate characteristics.
Cross-inoculation experiments revealed that O.
cumana populations collected on wild species possessed similar ability to parasitize sunflower to those collected on sunflower.
The results were explained on the basis of an effective genetic exchange between populations parasitizing sunflower crops and those parasitizing wild species.
The occurrence of bidirectional gene flow may have an impact on wild populations, as new physiological races continuously emerge in weedy populations.
Also, genetic variability of wild populations may favour the ability of weedy populations to overcome sunflower resistance mechanisms.
