Abstract

AbstractChromosome pairing, chiasma frequency and distribution as well as chromosome segregation were analyzed in 13 populations of Foeniculum vulgare. All populations possessed n = 11 (2n = 2x = 22) chromosome number forming mainly bivalents with some amount of quadrivalents possibly due to the occurrence of heterozygote translocations. Cytomixis and desynapsis occurred in all populations leading to the formation of unreduced pollen grains. Cluster analysis of meiotic data showed distinctness of the populations in their meiotic behavior.
