- Abstract
Yellow Mosaic Virus disease (YMVD) is a common and destructive disease of soybean that can result in yield reduction upto 80% in severe cases. In the present investigation, comparison of antioxidant system and biochemical constituents in seeds of susceptible and resistant soybean genotypes against YMVD was carried out. Susceptible genotypes contained lower contents of total sugars and sucrose as compared to individual tolerant genotypes as well as mean values of all the genotypes. Tolerant genotypes exhibited significantly lower contents of total phenols, flavonols, hydrogen peroxide, malondialdehyde (MDA), glutathione and proline as compared to seeds of susceptible genotypes. Peroxidase, glutathione-s-transferase, glutathione reductase activities were lower in seeds of tolerant genotypes as compared to susceptible ones whereas polyphenol oxidase and catalase showed the reverse trend. Significant variations in superoxide dismutase (SOD) activity within tolerant and susceptible groups were recorded and the mean SOD activity was higher in susceptible genotypes than in tolerant ones.
