Seed is the unique biological input in agriculture, which imbibes in it the productivity potential of the crop. This potential in terms of both quantity and quality is realisable by the timely use of other inputs. It is therefore important to plan and produce adequate quantities of good quality seed to realise enhanced agricultural production and higher income to farmers. The use of high quality seed will enable to reduce the gap between potential and actual yield of all crops.

Seed industry in India has made great strides especially during last twenty years. The Government of India through its policy initiatives has encouraged development of this industry. A lot of attention has been paid to organizational, legislative and financing aspects, resulting in enhanced seed multiplication. Today, after the introduction of genetically modified crops, the Seed Industry has acquired a paradigm shift.

This situation warrants proper functioning of effective quality control system to assure the quality of the seeds through standard seed analysis system. In this view knowledge on recent approaches in seed testing is highly essential for a seed men, seed testing and seed law enforcement officials and seed scientists. Keeping this in mind, the book, A hand book of seed testing designed clearly, explains the scientific methods of analysing different seed quality traits. The book details procedures of routine seed testing methods and recent approaches in seed testing.
