Laboratory and field experiments were conducted to investigate the relationships between germination characteristics and field emergence in produced seeds of soybean cultivars as affected by under three different soil moisture conditions. The treatments are included water stress [Irrigation plants after 50 (Normal irrigation), 100 (Mild stress), 150 (Severe stress) mm evaporation from class A pan] and cultivar [Manokin, Williams and SRF×T3 Line]. Quality test was conducted factorial based on completely randomized design with four replications and field emergence factorial based on randomized completely block design with three replication. Results showed that in laboratory tests drought stress had significant effect on mean daily germination, seed viability and seed vigor. Experimental treatments had no effects on seedling emergence from sand in pot experiment and field condition. Germination in standard germination test had significant correlation with Germination in cold test. Seedling emergence in field had relationship with germination in standard germination test, cold test and accelerated ageing test and therefore can with using these tests predict field emergence.
