In: Mansoura University journal of plant production 2012.v.3(8)Summary: The present study was carried out at Sakha Agric. Research Station during 2011 growing season to study the germination and early seedling growth and physiological attributes of five soybean (Glycine max L Merr.) cultivars (Toano, Giza 35, Giza 111, Giza 22 and Giza 83, beside the five breeding lines H32, DR. 101, H9L186, H6L136 and H2L78) under different levels of saline water. Two experiments were conducted first experiment on Petri dishes and the other in pots and saline water concentration, were 0, 6 ds/m 9 ds/m, 12 ds/m and 15 ds/m. The obtained results proved that the genotypes under study could be arranged into three groups according to their sensitivity to salinity stress. The first group included the genotypes DR 101, Toano, H2L78, H9L86 and Giza 83, which are the most tolerant to salinity due to the high germinability and vigorous growth to development for whole plant under all levels of salinity.
