Characterization of fifty one landraces of rice was done using 46agro-morphological traits following Distinctiveness, Uniformity and Stability test (DUS)during kharif season of 2008 2009 and 2010 at the Zonal Adaptive Research Station,Krishnagar, Nadia, West Bengal. Out of fifty one varieties studied, twenty seven werefound to be distinctive on the basis of twenty two essential and twenty four additionalcharacters.
