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.
