Thirty-five accessions of Panicum maximum Jacq were collected from parts of the states of South-western Nigeria to determine the karyotype. The chromosome number is 2n = 32. They are largely sub-metacentric medium small, only chromosome pair one is submetacentric medium large. All accessions studied have symmetrical karyotype. The katyotypic pattern shows that the chromosomes can be grouped into eight groups of four and some size differentials are also recognized within each of the groups. Mitotic metaphase chromosome characters were used to assign the karyotypic formula 1Csm + 15Bsm for P. maximum.
