Abstract :Today beside ionizing radiation, chemical mutagens are also used in crop improvement and Ethylmethanesulphonate insert ignore into journalissuearticles values(EMS); is one of the most widely used chemical mutagens in the field of plant breeding. This research work was carried out to determine the effect of chemical mutagen insert ignore into journalissuearticles values(EMS); on seedling height. TAEK A-3 and TAEK C-10 soybean varieties were used as the test plants and effect of presoaking time determined. In greenhouse and field experiments five different EMS doses insert ignore into journalissuearticles values( 0 insert ignore into journalissuearticles values(Control);, 0,025, 0,050, 0,075 ve 1,0 M); and in greenhouse 3 different presoaking time insert ignore into journalissuearticles values(0, 6 and 18 hours);, in the field 2 different presoaking time insert ignore into journalissuearticles values(0 and 6hours); were applied. After chemical mutagen application in the green house germination percentage and seedling height base EMS dose and presoaking time effect had been determined. Effects of EMS in M1 germination of soybean for different characterics insert ignore into journalissuearticles values(no. of plants, plant height, no of pods and seedyield); were determined under field condition. As a result it can be said that in both soybean varieties, seedling height was reduced as the EMS concentration increased. But there was no distinct influence of presoaking time on the seedling height in both soybean varieties. In both soybean varieties the average percentage of germination increased with increasing pre-soaking time. Based on results obtained in field experiment, it was concluded that by 6 hours presoaking the harmful physiolojical effect of EMS could be decreased.
