In: Egyptian Journal of Plant Breeding 2008.v.12(1)Summary: Sweet sorghum were assessed in seasons 2006 and 2007for salt tolerance on basis of the traits; plant height, shoot fresh weight, shoot dry weight, root dry weight, root length, total chlorophyll and shoot/root ratio. The sweet sorghum cultivars were Atlas, Umbrella, Planter, MN 3556, Leoti, Smith, Honey, MN 4418, Sugar Drip, MN 4490 and Rex. Also molecular genetic fingerprints for these cultivars using SDS-PAGE protein markers was determined. Rex, MN 4490 and Umbrella were the highest cultivars in the studied traits under salt stress (the most salt tolerant cultivars) as they had the highest rank for all the traits while, Atlas, Leoti and MN 4418 showed the lowest rank in this respect. The banding patterns of the four protein assessments, i.e., total protein, water-soluble protein, water-nonsoluble protein and kafirin revealed wide variations of different bands (22, monomorphic and 65 polymorphic bands). The relationships among sorghum cultivars based on the overall polymorphisms were in partial agreement with the known lineage of these cultivars.
