This study deals with the detailed analysis on various meiotic abnormalities in the tetraploid cytotype (2n=4x=48) of Physalis peruviana L. The meiotic abnormalities include secondary associations of bivalents, stickiness of chromosomes, multivalents and univalents, and unoriented bivalents during metaphase-I, non-synchronization in the separation of some bivalents, laggards, chromatin bridges and cytomixis at various meiotic stages besides aberrant microsporogenesis. In spite of all these abnormalities, distribution of chromosomes at anaphases found to be normal. Microsporogenesis includes monads, dyads and tetrads with micronuclei besides normal tetrads, consequently reducing the pollen fertility (76%).
