Management of potato diseases through host resistance

Potato is one of the very few crops in the country where host resistance has been exploited to the maximum. Resistance varieties against large number of diseases have been bred and deployed across the country. Diseases for which resistance has been incorporated include; late blight-23 varieties, early blight-9, PVR-1, PVY-2, PLRV-2, wart-8, cyst nematodes-2. Several of them posses multiple disease resistance. Genetic engineering is being exploited to develop transgenes against potato pests (potato tuber moth) and late blight. Few PTM resistant lines have already been developed which are under glasshouse tests. However, as mentioned in the beginning, resistance is only one of the components of disease management. Other alternatives and complementary methods have also been integrated with host resistance to develop a sound Integrated Disease Management system for potato crop. Seed-plot Technique developed by CPRI in 1968 and subsequently refined is the most illustrious example of Integrated Diseases and Pest Management in the country which needs to be emulated in other important crops.
