Cytogenetic Studies in Some Irano-Turanian Populations of <i>Crepis foetida</i> subsp. <i>rhoeadiflolia</i> (Asteraceae) from Turkey

Irano-Turanian floristic region in Turkey appears to be the center of origin Crepis foetida subsp. rhoeadiflolia (Asteraceae). In this study, karyotype and flow cytometric analyses six populations C. were performed. The cytogenetic characteristics using multivariate (cluster analysis, principal components analysis) evaluated a cytogeographic context. Two main groups are found based on among distribution pattern. significant differences mainly concern long length chromosome, centromeric index, genome size. ecological evolutionary value data discussed within framework results obtained.
