1. Characteristics of Good Quality Seeds

2. Introduction Seed Quality is defined as variedly pure with high germination percentage, free from disease and disease organisms, and with a proper moisture content and weight. Quality seed insures good germination, rapid emergence, and vigorous growth.

3. Classes of High Quality seeds Rice TAG COLOR SEED CLASS White Tag Breeder Seeds (BS) – produced from uniform panicles (nucleus seeds) Red tag Foundation Seeds (FS) – produced from breeder seeds Green tag Registered Seeds (RS) – produced from foundation seeds Blue tag Certified Seeds (CS) – produced from registered seeds

4. SEED GRAIN It should be viable Need not viable It should have maximum genetic and physical purity Not so Should satisfy minimum seed certification No such requirement Treated with pesticide/fungicide to protect seed against storage pests and fungi Not treated with any chemicals since used for consumption Respiration rate and other physiological and biological processes should be kept at low level during storage No such specification Production is technically organized Not so It should satisfy all the seed quality attributes No need

5. Benefits of using quality seeds They are genetically pure (true to type) The good quality seed has high return per unit area as the genetic potentiality of the crop can be fully exploited. Less infestation of land with weed seed/other crop seed. Less disease and insect problem. Minimization of seed/seedling rate, fast and uniform emergence of seedling They are vigorous, free from pest and disease. They can be adopted themselves for extreme climatic condition and cropping system location.

6. 8 .The quality seed respond well to the applied fertilizer and nutrients. 9 .Uniform in plant population and maturity . 10. Crop raised with quality seed are aesthetically pleasing. 11. Good seed prolongs life of variety. 12. Yield prediction is easy. 13. Handling in post-harvest operation will be easy. 14. Preparation of finished products are also better. 15. High produce value and their marketability.

7. SECURING SEEDS 2 ways of securing seeds to plant: You can buy seeds from seed stores or order from reliable sources. You can produce your own seeds to plant Factors to consider in securing your seed to plant: Varieties should be adopted to your locality Quality of the product

8. Advantages of producing your own seed: you shall have an ever ready supply of seeds for your farm. Higher percentage of germination is assured Improvement of quality and quantity of product is possible. Disadvantage of producing your seed: Seed growing is an exacting work. It competes with the normal work in the nursery management. It calls for knowledge of the principle of plant breeding. It calls for keen observation It requires close application of details.
