The experiment was arranged in a randomized completely block design with three replications. The growth-related traits were recorded at the time of flowering and harvesting. Number of pods/plant, number of seeds/pod, 100-seed weight and final seed yield were collected at harvest. The salinity of irrigation water observed in Long Phu (EC = 2.27-2.56 mS/cm) is higher than that of Chau Thanh (EC = 1.9 mS/cm), and peaked at ECvà gt
4 mS/m which is considered as saline water. As a consequence, the soybean lines in Long Phu had lower yield components and seed yield than those planted in Chau Thanh. Seed yield (g/plant) of Chau Thanh and Long Phu were for the line(s) MTĐ 878-2 (4.7 and 2.52)

71.4 and 28.0%, respectively. The seed yield of the line 31000-2 was decreased at the smallest percentage (28%) under saline irrigation in Chau Thanh and Long Phu.
