Karyotype analysis and male meiotic behavior in a bulbaceous plant Drimiopsis kirkii were studied. The somatic chromosomes in 2n=66 were ranged between 1.50 – 9.72 µm in length. The karyotypic formula was 2n=66=30m+14sm+16st+6t. The haploid set of 33 chromosomes were counted in mitotic metaphase of pollen grains. Detailed meiotic analysis from PMCs to tetrad were carried out and most of the PMC underwent normal meiosis to form the microspore tetrad. However, 7.8 % PMC showed various meiotic abnormalities in form of univalent or bivalent laggards, late separation, anaphesic bridge, chromosome fragments etc.
