Abstract: The present investigation was carried out at laboratory of Department of Seed Science and Technology OUAT Bhubaneswar. To characterize aromatic short grain rice varieties by using standard phenol test. The phenol reaction is controlled by the tyrosinase enzyme in the seed coat and it is under genetic control. The phenol colour test is the index of polyphenol oxidase activity, a simple, quick and accurate test for the distinction of cultivars. In the present study, among thirty aromatic short grain rice varieties eleven aromatic short grain varieties reacted positively whereas remaining nineteen aromatic short aromatic grain rice varieties reacted negatively to standard phenol test. Based on standard phenol test, the aromatic short grain rice varieties were classified in to four groups as no change in colour (V3, V4, V7, V9, V11 V13, V14, V15, V16, V17, V18, V20, V21, V24, V25, V26, V27, V28 and V29) light brown (V5, V6 and V19), brown (V22) and dark brown (V1, V2, V8, V10, V12, V23 and V30). Thus based on the colour reaction of palea and lemma of seeds to standard phenol test can be effectively distinguished.
