Abstract

During 1999/2000 and 2000/2001, a total of 136 and 108 barley genotypes
besides five Egyptian cultivars were evaluated for salt-tolerance in a series of field
experiments at four locations. The soils of these locations were carefully selected to
represent different degrees of salinity level. The obtained results showed marked
variation among genotypes concerning the studied characters. The genotypes
significantly differed in plant height, biological yield and grain yield. It was possible to
identify some barley genotypes that could survive under salt stress conditions.
Therefore, those genotypes proved again their ability to tolerate soil salinity. Yield
stability parameters proved that ten genotypes appeared to be the most stable
genotypes and could tolerate saline stress. Those genotypes are of great important in
breeding point of view and should incorporate in the national breeding program for to
increase yielding ability under salt stress environments
