COMPARATIVE KARYOMORPHOLOGICAL STUDIES OF TWO SPECIES OF CRINUM

Crinum asiaticum L. and Crinum latifolium L. are members of the family Amaryllidaceae. Karyomorphological studies of these two species had been performed by using different quantitative and qualitative parameters to know the karyotype asymmetry, which defines the advanced and primitive nature of these two species. The study revealed that Crinum asiaticum L. and Crinum latifolium L. are diploid with 2n=22 chromosomes. based on Total Chromatin Length, Arm Ratio, Gradient Index, Form Percentage, Total Form Percentage, Karyotype Asymmetry Index, Symmetry Index, and Stebbins classification, Crinum asiaticum L. is more advanced than Crinum latifolium L.
