ABSTRACT:

The karyotypes of diploid (2n = 2X 28) and tetraploid (2n = 4x = 56) forms of Alocasia odora (Roxb.) K. Koch were analyzed to determine their cytological relationship. The chromosome length and morphology were found similar between the two ploidy types. Phylogenetic relationship investigated by polymorphism of 13 enzyme systems also suggested closeness of the two ploidy types of A. odora.
