Abstract

Variation in concentration of Piper yellow mottle virus (PYMoV) and Cucumber mosaicvirus (CMV) in stunted disease infected black pepper plants from different varieties/cultivarsduring different months of a year was studied by DAS-ELISA. Higher A405 values wererecorded from October to February in four varieties/cultivars of black pepper tested andPanniyur-1 had the highest concentration of both the viruses. Results on distribution ofthe viruses within a plant from three varieties/cultivars showed that young leaf containedhighest concentration of both the viruses while root region recorded the least. A total of2186 black pepper nursery plants from eleven varieties were indexed by DAS-ELISA for thepresence of viruses. Of these, 714 plants were found infected with either of the two viruses.Among these, IISR-Sreekara had the highest number of infected plants followed by IISR-Subhakara while Panniyur-5 had the least number of infected plants. Of the 714 plantstested positive, 390 plants exhibited no visible external symptoms indicating the necessityfor sensitive diagnosis in identifying virus-free planting material.
