Sažetak
The studies of population genetics of Orobanche species are of great importance since the understanding of the variability within and between pathogenic populations is essential if selection programmes need to target sources of resistance in different areas and suitable breeding strategies need to be developed. The use of morphological markers in Orobanche has been difficult because holoparasitism resulted in a reduced number of suitable characters even for taxonomical purposes. The distribution of genetic variation in O. aegyptiaca, O. crenata, O. cumana, O. foetida and O. ramosa populations has been reviewed based on available molecular marker data. It is shown that by using simple DNA marker systems (e.g. RAPDs and ISSRs) the intraspecific variability can be assessed and problematic issues such as the differentiation between botanical taxa, geographical differentiation, and host-differentiation can be addressed.
