摘要：

The holoparasitic Orobanche cumana Wallr. has become a limiting factor for sunflower yield in Eastern Europe. Better knowledge of broomrape biology, including genetic diversity, is important in any attempt to develop resistance-breeding programs. There is little information available on the diversity of broomrape in the Republic of Moldova. The aim of this study was to evaluate the interpopulation variability of the Orobanche cumana Wallr. using Inter Simple Sequence Repeats (ISSR) markers. Data from the present study revealed that ISSR marker system could be used for estimating genetic diversity, since it had high percent polymorphism. All of the genetic parameters indicated that the populations from Center are genetically different from those collected in the South and North regions of the Republic of Moldova. The results of genetic polymorphism showed that the application of 14 ISSR markers made it possible to group the studied 39 broomrape populations into different clusters. The association with geographic origin was established.
