Abstract

Strain Selection of Soybean ( Glycine max (L) Merril) of F3 Generation on Saline Soil. Salinity isone of the most serious and widespread agricultural problems resulting in losses of yield. Generally,as land is more intensively cultivated, the salinity problem becomes more severe. A highconcentration of NaCl greatly reduces growth of both the shoot and the root. One strategy availableto cope with saline soil is to choose salt-tolerance crops or to select salt-tolerance cultivars within acrop. This research aims to select the soybean that can grow and has a higher production on salinesoil of F3 generation. This research was conducted in the experiment area at Desa Tanjung Rejo,subdistrict of Percut Sei Tuan, Regenecy of Deli Serdang in the elevation of 1.5 m on above sealevel since Apryl 2012 up to Juny 2012.
