In the present investigation, characterization of seventy landraces of rice was carried out based on fourteen DUS characters. Out of fourteen characters under study, stem anthocyanin colouration of node was dimorphic. Three traits viz., spikelet colour of stigma, stem length and panicle exsertion were trimorphic. Basal leaf sheath colour, time of heading (50 % plants with panicles), flag leaf attitude (late observation), panicle length, decorticated grain length and shape were tetramorphic and lemma anthocyanin colouration of apex and amylose content showed five states of expression and based on decorticated grain colour six groups were made.

Key words: Agro-morphological, Characterization, DUS descriptors, Rice, Landraces.
