Pakistan''s domestic edible oil production doesn''t meet the need of the country. Annually about $1.5 billion is spent on its import to meet the demand. In this way, edible oil stood at the top in the import of food group and on number second after petroleum group in the total import. This huge drain on our hard-earned foreign exchange resources is a great challenge for our planners, agricultural scientists and extension workers. Any attempt to help in amelioration of this worsening situation is the need of the day. Among existing oilseed crops rapeseed/mustard and sunflower have assumed special position in the agriculture economy of Pakistan. Much of the research efforts have been directed towards the improvement of these oilseed crops. The book in hand can furnish baseline information and is highly recommended for every agricultural library.
