摘要：Nuclear and chromosome characteristics of seven varieties of Colocasia esculenta were studied. Interphase chromosome value was found to range from 2119.85 (cytotype-3) to 5346.12 (cytotype-7). Heterochromatin values varied from 23.17 (cytotype-2) to 44.52% (cytotypt-6) in meristematic cells. Karyotype studies revealed that somatic chromosome number was 28 in cytotype-1, 2, 5, 6 and 7; 42 in cytotype-3 and 21 in cytotype-4. The longest chromosome (5.54 μm) was observed in cytotyopt-2 and shortest (1.3 μm) in cytotype-3 and 6. Key words: Karyotype, Nuclear phenotype, Colocasia esculenta.
