Setaria BEATJV. is an important genus of the tribe Paniceae of the family Gramineae. Seventeen species from the genus have been listed by BOB, 1960 from Burma, Ceylon, India and Pakistan. However, no detailed biosystematic work in the genus has ever been undertaken. The genus was,therefore, selected by the authors for intensive study. Collections have already been made from Hastinapur, a place having luxuriant vegetation and located 36.4 kilometers north-east of Meerut. During these collections plants belonging to Setaria verticillata were collected several times and the cytological study revealed that only hexaploid race was represented. The diploid, tetraploid and hexaploid chromosome counts were already known in the species (AVDULOV 1931, 2n = 36; DE WET 1954, 1956, 2n = 18; and MEHRA & al. 1968, 2n = 18, 36, 54). In these earlier reports, meiosis was reported to be normal at all the three ploidy levels. In the present study, material from number of plants collected at different times, was studied. Meiosis was always found to be abnormal. The details of abnormal meiosis in this taxon are being reported in this paper.
