Recent Topics Posters Mostafavi, Golaleh [1], Salimpour, Fahimeh [2]. The Biosystematic study of Trifolium genus(Lotoidea Section)in Iran. The Lotoidea section of the genus Trifolium consists of 2 annual and 5 perennial herbaceous species in Iran. Its range of distribution extends throughout North, North – West and some parts of Iran Center. Biosystematic studies were used to identify the relationships between the species in this section and with representative species of another sections of Trifolium genus. A cluster analysis of morphology, pollen and seed characterestics divided the examined species into some groups. A factor analysis determined the sources of changes between species. Based on these observations, pollen features are not capable for seperating the species lonely, but it excessively confirms with the results of morphological traits. Seed micromorphological studies showed the effeciency of these characters to separate the similar species. According to karyological studies, the basic chromosome number in all examined species was x=8. Most of these species were polyploid and had different karyotype. So these characters, have a significant role to separate the similar species in section Lotoidea. Based on these results, the tetraploidy state in T. nigrescens and T. montanum is reported from Iran for the first time.
