Biochemical Alterations in Different Pigeon Pea Genotypes due to Sterility Mosaic Disease

Background: The sterility mosaic disease in pigeon pea caused by virus is a serious threat to cultivation India. A little information available on the biochemical changes plant against SMD disease. Hence present study was taken know alterations different genotypes due Methods: Studies were conducted composition of chlorophyll pigment, total soluble protein (%), sugars, phenol, tannins, peroxidase and phenol six genotypes. Result: results showed that there reduction pigment composition, (%) sugars all infected genotypes, but resistant less compared other In amounts phenols, increased, where as susceptible they roughly equal uninoculated increase can be correlated with resistance.
