Abstract
To enhance theoretical basis of Aloe feeding and provide cytological basement, the karyotype and morphology of mitotic chromosomes, ten different populations of Aloe vera collected from various geographical locations of Karachi, Pakistan were studied by aceto-orcein staining technique. The results showed that chromosome number of Aloe vera is 2n=14. The karyotype is bimodal and consists of 14 chromosomes (8 large and 6 small) predominantly with submedian, median and subterminal centromere. Average chromosome lengths among populations ranged from 7.95-2.36 μm.
