Abstract

Biochemical changes for fifteen sugar beet genotypes (Pleno, Gazela, H-Poly1, Oscar poly, Toro , Kawemera, Disprerez PolyN, Demapoly, Farida, Karola, Negma, Baraka, Gloria, Top and Chems) in relation to yield and its components were studied during 2007/2008 and 2008/2009 seasons under saline conditions at Ras Sudr, Sourth Sinai. Sugar beet genotypes greatly varied in their ability to grow and subsequently to assimilate and translocate biochemical components. Pleno and Gazela surpassed the other genotypes in root diameter, root weight and root yield. Oscar poly and Pleno genotypes recorded the highest mean values for sugar yield, followed by Gazela genotype in a descending order. These findings associated with the highest values of some biochemical constituents such as photosynthetic pigments, proline, soluble protein, RNA and decreased in malondialdehyde content as compared with the other genotypes. Impurities content and sucrose% were affected by genotypes and salinity. This study is showing that sugar beet genotypes such as Pleno, Gazela as well as Oscar poly were highest in their productivity and salt tolerance, also studied biomarkers are benefit to determine best inducers against sensitivity to salinity.
