Stability Analysis and Molecular Description of Some Promising Sorghum Lines Tolerant to Salt Stress

<b>Background and Objective:</b> Salt stress is considering the biggest environmental obstacle to crop productivity, especially sorghum. So, it was necessary to develop new sorghum lines tolerant to salt stress and high yielding to participate in bridging the large gap in the Egyptian bread industry and also as an important feed for animals. This is the biggest goalie this investigation. <b>Materials and Methods:</b> Some promising sorghum genotypes were evaluated under the control experiment and two salinity stress locations to test their stability and its salinity stress tolerance during two years. Some agro-morphological and physiological traits were the most important parameters tested under all conditions besides, 11 SCoT primers for comparing among the seven sorghum genotypes and Identification of molecular genetic markers responsible for salt stress tolerance. <b>Results:</b> The final results revealed that the five promising sorghum lines were recorded highly rank of salinity stress tolerance in all studied traits and a higher level of genetic stability during the two years. <b>Conclusion:</b> Results of agro-physiological traits, salinity tolerance indices and SCoT primers succeed in determining salt stress tolerance mechanisms in sorghum and which an important taxonomic tool is for plant breeder that helps him in sorting the tolerant genotypes from the sensitive ones.
