Keywords:Potato seed production and certification systems, conventional and hi-tech seed production, virus profiling and their vectors
Potato is an important food and cash crop globally and its production is hampered by inadequate supply of
good quality seed tubers. Potato, being a vegetatively propagated crop, gets degenerated very fast necessitating replacement
of seed very frequently. Slow multiplication rate and high volume of seed requirement poses a unique challenge to potato
seed production. A paradigm shift in potato seed production methods has taken place globally since early 1900s. Major
potato producers of the world have shifted from conventional system of seed production to hi-tech seed system to improve
the seed quality. Potato seed production and certification systems followed over the years, profile and dynamics of potato
viruses and their vectors, and challenges ahead for seed production under climate change scenario are described here.
