Abstract

Chromosome number, meiotic behavior, and pollen viability were analyzed in 2 species of genus Solenanthus, S. stamineus (Desf.) Wettst. and S. circinnatus Ledeb, from Iran. This report is the first cytogenetic analysis of these species. All taxa are diploid and possess 2n = 2x = 24 chromosome number, consistent with the proposed base number of x = 12. Although this taxon displayed regular bivalent pairing and chromosome segregation at meiosis, but some abnormalities were observed.
