In: Egyptian Journal of Agricultural Research 2012.v.90(4),SISummary: The present investigation was carried out to study the inheritance of salt tolerance in six parental barley genotypes (Hordeum vulgare L.), under sand culture screening experiment. These genotypes differ genetically in their salt tolerance potentiality, and their F1. The aim of the study to estimate general and specific combining ability (gca and sca) as well as heterosis for yield and its components and genetic components. Also to develop biochemical and molecular markers associated with salt tolerance for the six parental genotypes, under control and salt conditions. Four crosses exhibited significant positive heterosis, these were (Rihane- 03 x Giza 123), (Rihane -03 x Line 2), (Rihane -03 x Line 4) and (Line 2 x Line 4). F1 hybrids had significant heterosis for four or more traits contributing to grain yield and it could be concluded that these crosses would be efficient for salt tolerance.
