| Abstract | ||||
| A field experiments including 63 exotic barley genotypes were conducted at three locations (Nubaria , Gin and Fayoum) in two growing seasons (1998.1999 and 1999-2000) . Each entry was planted in four rows per plot in randomized complete block design with three replications. Results showed that six genotypes were earlier and ten were the tallest than national check NC (Giza 125) by about 9 days and 8 cm, respectively. Genotypes No.. 56, 54, 34. 7 and 6 had the heaviest kernel weights (47.9, 47.58. 47.0, 46.24 and 45.74 gm., respectively). Grain yield and barley disease the field results showed that 20 genotypes had high yielding potential and good reaction for Powdery Mildew (PM) and Leaf Rust (LR). According to the stability parameters eleven entries were more stable with good reaction of PM and LR. The chemical or:impositions revealed that protein content ranged from 12.33% in genotype No., 56 to 14.54% in genotype No., 15 while total carbohydrates ranged from 72.63% in genotype No., 35 to 78.28% in genotype No., 44. Polyacrylemide gel electrophoresis (PAGE) technique could be dearly differentiated between some genotypes. Although some groups of genotypes gave similar hordein and albumin-globulin mixture patterns. They could be discriminated by some differences by minor components. | ||||
