Abstract:

Sterility mosaic disease (SMD) is one of the major biotic problems for pigeonpea production in the Indian subcontinent. A systematic survey and comprehensive study was carried out to determine the incidence of Pigeonpea sterility mosaic virus (PPSMV) and molecular variability among disease causing agents in Tamil Nadu state of southern India during the 2019Kharifseason. The results indicate there was a variation in SMD incidence among the districts. In Tamil Nadu SMD incidence was observed ranging from 3.6% to 21.3%. In this study we analysed the SMD infected samples from 12 locations of major pigeonpea growing regions of Tamil Nadu state. All isolates contain both PPSMV-1 and PPSMV-2 as mixed infection none of the sample was positive for PPSMV-I or PPSMV-2 alone. Overall our study provides evidence for variability and increase in disease incidence.
