Twenty soybean cultivars were grown at the University of Agriculture Makurdi Teaching and Research Farm in July 2006 and harvested October 5th and November 7th 2006 according to the time physiological maturity of the varieties. From each harvest population of the different culture, the moisture content and dry matter weight (oven method, 105oc for 72 hours) were determined for samples of 10 seeds per replicate. The seed were stored under normal environment condition in cotton bags which were tied and kept for 7 months. Seed moisture contents were determined at different stage of storage. The germination test was performing according to the International Seed Testing Association in the Crop Science Laboratory of the University of Agriculture Makurdi, Nigeria, located on longitude 8.37oN. Within the Southern Guinea Savannah agro ecological zone of Nigeria. The results indicated that TGX 1838-5E and TGX 1440-1E showed higher viabilities by recording greater germination percentage. Doko, TGX 1896.3F and Milena soybean varieties recorded higher germination index while lowest germination index occurred in TGX 1844 – 18E. The medium maturing type had the highest mean germination percentage (54.32%) followed by late maturing varieties.
