Abstract

Annual oilseed crops in India occupy an area of 27 million ha with the production of about 30 million tonnes. More than 70% of the oilseed cultivation occurs in resource-poor rainfed areas and is prone to several seed-borne diseases, which lead to low productivity. The reduction in seed germination due to seed rot and seedling mortality reduces the plant population level to below optimum; besides seed-borne pathogens contaminate the areas which were disease-free previously. Seed-borne diseases due to presence of pathogen either internally or externally on seed or on vegetative propagating materials or as concomitant contamination are potential threat to cultivation of annual edible oilseed crops. This chapter deals about symptomatology, aetiology and economic importance of seed-borne diseases of cultivated annual edible oilseeds, viz. peanut (groundnut), sesame, soybean, rapeseed-mustard, sunflower and safflower.
