This research aimed at studying the effect of location, sowing date. The experiment was carried out in the growing season 2012/2013 under Sudan conditions using two sowing dates; optimum sowing date, and late sowing date, at two locations; Shambat in Khartoum state and Hudeiba in the River Nile state. The experimental design was a split-plot with three replications. Seeds were tested for seed moisture content, falling number, seed germination percentage and rate of germination. Results revealed that the effect of location was highly significant for both falling number and rate of germination, and was significant for germination percentage. There was no significant effect of sowing date on all studied seed quality characters. The effect of genotype was highly significant for falling number and non-significant for the other three traits which were positively correlated with rate of germination at the two locations.
