Salient Achievements:
• Methodology developed for detection and identification of viruses in germplasm by using a strategic combination of Electron Microscopy (EM), Enzyme-linked Immunosorbent Assay (ELISA) and Reverse Transcription- Polymerase Chain Reaction (RT-PCR) by which 45 viruses including 19 viruses not reported from India such as Cherry leaf roll virus (CLRV) and Tomato ring spot virus (ToRSV) were intercepted. The major impact is the exclusion of viruses which could have lead to economic yield losses, if these were not intercepted in quarantine. This also facilitated conservation of virus-free seeds of introduced germplasm in National GeneBank.
• Established modern virology laboratory in Division of Plant Quarantine, ICAR-NBPGR, New Delhi which is of international standard.
• Developed a multiplex RT-PCR method for simultaneous detection and discrimination of three viruses (CLRV, ToRSV and GFLRV).
• Prepared pathway-based country-specific generic Pest Risk Analysis for 190 crop species with reference to viruses of which 140 were notified in Gazette.
• Database on Potential Quarantine Pests (PQPs) of cereals, grain legumes, oilseeds and tropical and sub-tropical horticultural crops has been developed as a ready reckoner to quarantine scientists and officials of NPPO.
• Developed three high-yielding, disease resistant varieties viz., Arka Arunima (amaranth), Arka Anupama (spinach) and Selection-9 (carrot) along with breeders.
• Prepared a national map of seed-transmitted viruses of grain legumes based on surveys in 9 states for 3 years and by testing 1842 seed samples from 21 states. The results identified some virus-free sites.
• Seed standards for certification against viruses of pea and soybean were developed.
• Human resource developed through Trainings “Biosecurity and Biosafety”, “Diagnostic Methods for Detection and Identification of Pests” and “Biosafety of Transgenics and Detection of GMOs”.
• Organized 14 Training Workshops on “Strengthening Capacities of Enforcement Agencies (Plant Quarantine and Customs Officials) for Transboundary Movement of living modified organisms” during 2015 to 2018. Training Workshops, each of two days duration have been organized for the plant quarantine and customs officials at different parts of the country. A total of 385 officials, which included Deputy Commissioners, Assistant Commissioners, Deputy Directors, Assistant Directors, Superintendents, Inspectors, Appraisers, Examiners, Preventive Officers from Customs and Joint Directors, Plant Protection Officers, Assistant Plant Protection Officers and Scientific Assistants etc. from Plant Quarantine were trained in these workshops.
