Abstract

This experiment was conducted to evaluate 15 sugar beet genotypes under normal and drought conditions based on completely randomized block design as split plot design with 4 replication in sugar beet seed institute in 1385.Main plots were irrigation treatments and subplots were genotypes. Results showed maximum SOD activity in drought treatment with 1796.48 (U/mg protein) and minimum activity in normal condition with 967.24 (U/mg protein) activity. There was no significant difference among genotypes for this enzymes. Correlation between ANTIOXIDANT ENZYMES and root yield was significant and negative. Maximum activity of CAT observed in drought treatment (111.9 (U/mg protein) and minimum activity observed in normal treatment (82.64 U/mg protein). Maximum amount of MDA was 54.27 (nm/mg protein) and minimum amount was 30.52 (nm/mg protein). There was negative correlation between MDA and root yield. Maximum protein degredation observed in drought treatment(15.49 nm/mg protein) and minimum degredation obtained in normal condition (12.47 nm/mg protein). There was a positive correlation between DITYROZINE and SOD, CAT and GPX. There was a negative correlation between DITYROZINE and root yield. There was also a negative but not significant correlation between DIHYDROXYGOANOZINE and SOD, CAT. There was significant differences in irrigation treatments for root yield. There was 35.1% improvement in normal condition in compare with drought treatment. There was significant difference among genotypes for WHITE SUGAR YIELD. Irrigation treatments had significant effects in white sugar percent. White sugar percent increased under drought condition about 58.86% in compare with normal condition.
