Abstract

In order to investigate ploidy levels in a THYME species (Thymus kotschyanus), three populations of the species growing in north and north-west of Iran were studied for cytogenetical aspects. Long arm length, short arm length and total length of the chromosomes, number of chromosomes and ploidy levels were studied at least in five mitotic cells of each population.A population (accession) from Sirachal station, (in central part of south slope of Alborz mountain chain) was tetraploid (2n=4x=60). The other two populations, collected from Tabriz and Mianeh were diploid (2n=2x=30). Regarding kariotypic symetric assessment parameters results such as TF%, DRL% and S%, tetraploid population was more symetric than the other diploid populations, particularly comparing to the Tabriz one. This implies that the Tabriz accession is in a more degree of evolution than the others. Based on the kariotypic symmetric parameters and range of the chromosomes total length, the two accessions of Tabriz and Mianeh are suitable for breeding purposes such as in traspecific hybridization and genetic variation induction.
