Abstract

Presently auto-octoploidy has been induced in an induced auto-tetraploid som, Persea bombycina (2n=24), the principal food plant of muga silkworm (Antheraea assamensis Helfer), through colchicine treatment (0.5%). Auto-octoploids showed deterioration in almost all the morphological features in contrast to tetraploid which seem to be the optimum ploidy level. Auto–octoploid is highly susceptible to stem diseases and dwarf in growth nature.
