Considering the importance of rice, a staple food crop which feeds millions of people around the globe, continuous crop improvement program has been under the way all over the countries and nearby about 2541 varieties have been released so for. Clear identification of exclusive crop varieties and hybrids are essential for the protection and prevention of unauthorized commercial use. In India, this is highly pertinent because the hybrid seed production and marketing of public sector hybrids is principally taken up by private sector (Nandakumar et al, 2004). Besides, supply of genetically pure seed of rice is vital to realize the gains accrued through rice breeding efforts. In order to maintain genuineness (true to type) and quality of seed, careful attention is needed at every stage of seed production of a variety. Hence characterization of 30 rice cultivars, two rice hybrids (KRH-2 & KRH-4) along with their parental lines viz, IR-58025A, KMR-3 and CRMS-32A, MSN-36 based on seed and seedling traits play an important to distinguish between cultivars. The characters such as seed size , seed shape, length,  seed colour, seed pubescence, seed awn, seed weight, decorticated grain shape, colour, length exhibuited more variation among the rice cultivars hybrids and their parental lines.
