A screen house and Laboratory experiments were conducted during the 2017 cropping season at the Teaching and Research Farm as well as the Plant Breeding and Seed Science Laboratory of the Federal University of Agriculture, Makurdi, Benue state, to investigate the effects of water stress on seed quality of soybean genotypes in Makurdi. The screen house experiment was basically to generate seeds for the Laboratory experiment. The experiment consisted of three soybean genotypes (TGX-1448-2E, TGX-1835-10E and TGX-1951-3F) which were subjected to water deficit stress at three different growth stages which included; early vegetative growth stage, 50% flowering stage, early pod filling stage and a well-watered treatment to serve as a control. The experiments were conducted in a Completely Randomized Design (CRD) with three replications. Parameters evaluated were germination percentage (G %), germination index (GI), germination rate index (GRI) and vigor index (VI). All data collected were subjected to the Analysis of Variance using Genstat 10.3DE package and significant means were separated using Fischer’s Least Significant Difference (FLSD) at 5% level of probability. Results from Analysis of Variance (ANOVA) showed that; Water stress highly significantly (p≤0.01) affected all seed quality parameters evaluated. Genotypic effect was also highly significant (p≤0.01) for all seed quality attributes evaluated. Germination percentage, germination index and germination rate index were highest in TGX-1448-2E. Water stress at the early pod filling stage significantly (p≤0.01) reduced seed quality in terms of germination percentage, germination index, germination rate index and vigor index in TGX-1951-3F but did not significantly affect seed quality in TGX- 1835-10E and TGX-1448-2E. TGX-1835-10E and TGX-1448-2E were therefore, more tolerant to water stress while TGX-1951-3F was the least tolerant.
