Standardisation of seed processing methods for hybrid rice was carried out at Department of Seed Science and Technology, TNAU Coimbatore. Considering, the high seed recovery and seed quality, 1.7 mm sieve can be used for size grading of TNRH-16 and TNRH-17 rice hybrids and 1.6 mm sieve for CORH-1 hybrid. Specific gravity separation of size graded seeds into four density grades showed the superiority of heavy, medium and light seeds over very light seeds in terms of seed quality parameters. Among the hybrids, CORH-1 showed its superiority in respect to seed quality over TNRH-16 and TNRH-17.
