      abstract = {The Amaranthus species are cultivated as pseudo-cereal because of their high content of carbohydrates, proteins and fats, comparable or even superior to cereals.  Many accessions of the crop exist and these have not been explored for a number of agronomic variables. The aim of this study was to determine seed   yield components of   the 27 Amaranthus accessions;     and   to   select   accessions   that    have   high   seed yield.  For   this reason,   a field   experiment   was   conducted   at the   University   of Ibadan,   Department   of Agronomy   Research   Farm on   27 Amaranthus accessions. The   following   variables were measured: seed germination, plant survival at 4 and 12 weeks after transplanting (WAT), plant height at flowering and 12 WAT, days to anthesis,  inflorescence  length  at   12   WAT,  fresh   and   dry   inflorescence weight, harvest index and seed weight (kg/ha). The highest seed weight was recorded for NGB/06/104; while NG/TO/JUN/09/008 gave the least seed yield among the accessions. Correlation   coefficients among   agronomic   variables ranged   from -0.0 (between   plant height at flowering and percent harvest index; also, dry inflorescence weight as percent of fresh inflorescence weight and seed weight in kg/ha) to 0.98 (between plant height at 12 WAT and plant height at flowering). Most of the 27 accessions evaluated varied in their inflorescence colour. Five of the accessions: NGB/O6/104, UI/OP/Mar/010/009, NHA/34BP1576468, NH/EI/Feb/010/006, and NG/OA/Aug/09/001 were selected in terms of higher seed weight, percent harvest index, plant height at 12 WAT, plant survival at 12 WAT, inflorescence length, and general superiority based on a multidimensional assessment determined by sum of weighted indices.},
