| Summary: | Salinity is a widespread soil problem limiting productivity of oilseed crops worldwide and soybean cultivars differ in their sensitivity to soil salinity. With this in mind, a pot experiment was conducted at plant nutritional physiology laboratory, Hiroshima University, Japan to study the response of three Egytp soybean cultivars (Giza-111, Giza-82 and Giza-35) to salinity stress (Control, 10 mM NaCl). The results showed that the culivars had a negative responce to salinity stress and most of the measured plant yield traits, oil and protein content. Results indicated that Giza-111 cultivar surpassed other cultivars in all characters under study. The highest value of seed yield, seed oil and protein percent observed in Giza-111 with the compare to other cultivars under salinity conditions. It was concluded that soybean is a sensitive plant to salinity stress, but the extent of this sensitivity varies among cultivars. As a result, Giza-111 cultivar showed more capability to survive under salinity condition compared with another cultivars regarding of almost all plant traits examined. Considering, Giza-111 was found more appropriate under salinity condition.
