Introduction, presented in the form of tabular form in this chapter. There are nearly 231 plant virus and viroid diseases which are reported to be seed transmitted from different parts of the world. Seed transmission of nearly 68 viruses is more common in leguminous species than in any other species of crop plan

Virus Transmission,While dealing with the insect vector transmission, the virus–vector relationship of some of the seed-transmitted viruses was also discussed. Doubtful reports of seed transmission of certain viruses by whiteflies and mites are to be confirmed by further studies. Information on role of pollen in seed

Detection of Plant Viruses in Seeds, IC-RT-PCR, multiplex PCR), are extensively practice. Protocols have been implemented in the field using portable real-time PCR machines for same-day, on-site results; cDNA probes which are labelled with radioactive markers or nonradioactive markers are used for diagnosis of seed-borne virus and vir

Ecology and Epidemiology of Seed-Transmitted Viruses,ons, the weed and wild hosts are important as they are the reservoirs for the virus, vector or both. Survival of the virus in the seed for a long period also plays an integral role in virus perpetuation in off seasons. Seed-transmitted viruses are also vector specific, and aphid or beetle or nematod
