High-quality seeds (HQS) are pure, full and uniform in size, viable, free from weed seeds and seed-borne pests, germinate well, and produce healthy seedlings. Breeder (BS), foundation (FS), registered (RS), and certified (CS) seeds are the various classes of HQS. Seed producers grow either FS or RS, while farmers are advised to use CS. The adoption of CS is one major factor that contributes to yield increase. This is asserted in the findings of the PhilRice-Bureau of Agricultural StatisticsÃ¢â‚¬â„¢ Rice-Based Farm Household Surveys (RBFHS).
