The International Union for the Protection of New Varieties of Plants (UPOV) promotes an effective system of plant variety protection and encourages the development of new varieties of plants. International convention was initiated to standardized the system efforts and strengthen the policy. This study was conducted to establish a database for rice identification using morphological characters which include number of tillers and panicle per plant, spikelets per panicle, yield, plant maturity, height, leaf pigments, flag leaf angles, and rice bran. The whole rice population was grouped into three based on leaf angles, majority members of which retained the flag leaf angle-character until maturity stage. Most rice accessions did not exhibit anthocyanin pigments on the leaves particularly on the first leaf, leaf blade, leaf sheath and auricle, except for varieties classified as black rice. In the case of grain, many accessions produced secondary branching, and showed no awn. For agronomic traits, productive tiller and panicle per plant were higher in early flowering varieties, while spikelets per panicle and ripened grain were higher in late flowering varieties, and yield was higher in medium flowering varieties. All data were then pooled for cluster analysis which revealed three major independent clusters and four minor clusters.
