Abstract: In this research, the cytogenetic characteristics, phases of meiosis, abnormality during meiosis, variety of pollen grains, and cytomixis phenomenon have been studied. Populations of 10 species belonging to Salvia L. have been collected from different geographical regions of Iran. Cytomixis was recorded during meiosis I in three species of Salvia (S. nemorosa, S. staminea, S. verticellata) of the Lamiaceae family. Cytomixis and other associated meiotic abnormalities such as chromatin stickiness, clumping of metaphase -1, laggards, bridges, aberrations anaphase I, II, and micronuclei in the species reported into pollen sterility and some variable sizes. It can be said all of these are dependent on each other to create some abnormalities. Cytomixis and chromosome migration occurre in diploid and polyploid meiocytes.
