Biochemical Impact Inflicted by Aphid Induced Urdbean Leaf Crinkle Disease (ULCD) Infection on Different Blackgram Genotypes

Aims: To investigate the variations in total protein content and anti-oxidative enzymes blackgram genotypes showing various levels of resistance against aphid-mediated Urdbean leaf crinkle disease (ULCD).
 Study Design: Completely Randomized Design.
 Place Duration Study: The studies were carried out at Insectary belonging to Department Agricultural Entomology Centre Innovation College Research Institute, Madurai, Tamil Nadu, India January 2021.
 Methodology: research was conducted on seven exhibiting different ULCD. A pot culture study established test plants subjected for inoculation urdbean virus (ULCV) via feeding by 10 viruliferous Aphis craccivora adults/plant. alterations content, superdioxide mutase (SOD), catalase (CAT) peroxidase (PO) activity estimated using spectrophotometric methods comparison healthy 0, 15 30 days after (DAI).
 Results: No discernible increase seen either ULCV inoculated or un-inoculated day inoculation. At post inoculation, highly susceptible (VBN 8 T9) only marginally higher than that resistant (CO 5 CO 6), whereas moderately genotype (APK 1) it had slightly increased. SOD showed a non-significant drop between versus plant leaves VBN T9 genotypes. significantly less observed, but PO inversely increased compared latter under conditions 6 While ADT did not show any significant conditions. Interestingly, considerably decreased reduced CAT both genotypes, when ones.
 Conclusion: Fluctuations antioxidant as well Days infection tends plants. aphid transmission inflicted considerable while decrease activities
