| dc.description.abstract | Present investigation reports the biochemical parameters in yellow mosaic disease (YMD) susceptible soybean genotype JS335, resistant genotypes G. soja (wild species) and G. max Cv. SL525 and resistant versions of JS335 introgressed with genes from wild/cultivated species. Leaves from different soybean genotypes were collected at 1, 10, 20 and 30 days post YMD infection under field conditions. Viral infection resulted in the formation of chlorotic yellow patches on leaf lamina and reduced leaf size of susceptible genotype JS335 whereas G. soja, SL525 and resistant lines of JS335 with G. soja (JS-GS) and SL525 (JS-SL) did not show disease symptoms. JS-GS and JS-SL lines showed higher seed yield and 100 seed weight as compared to susceptible genotype JS335. The activities of antioxidant enzymes [glutathione reductase (GR), glutathione-s-transferase (GST), peroxidase (POD), polyphenol oxidase (PPO) and superoxide dismutase (SOD)], phenolic constituents and non-enzymatic antioxidants (proline, glutathione, hydrogen peroxide, malondialdehyde and glycine- betaine) increased significantly from day 1 to day 30 post YMD infection with lower mean contents in leaves of JS-GS and JS-SL lines in comparison to diseased JS335 leaves at all the stages of crop development. Higher contents of total soluble proteins, total soluble sugars, reducing sugars and lipids were recorded in seeds of improved JS335 lines in comparison to susceptible JS335 whereas amino acids, phenolic constituents, sucrose and minerals showed the opposite trend. The resistant JS335 lines showed improved resistance to yellow mosaic disease and higher physiological parameters indicating them to be better in performance as compared to susceptible JS335 under local environment of Punjab. | en_US |
