A total of 97 landraces were collected by the exploration team from 41 villages of four different blocks viz., Tamnar, Gharghoda, Lailunga and Dharamjaigarh from Raigarh district. Based on the morphological and quality characters the diverse landraces were collected. The valuable landrace conserved by farmers  namely, Borojhari,  Boonde, Geeta, Saria, Thadvel, Bathras, Agiasal, Ratanchuri, Goirmal, Pangudi, 90 No., Ganga and Sonakathi. These valuable landraces possesses the characterstics such as fine grain, aroma, red pericarp, early maturity, submergence tolerance and good head rice recovery. The collected landraces will be utilized for the genetic enhancement and value addition of existing varieties of rice. Thus, it may be helpful not only in conserving the genetic resources but also exploit their potential in terms of yield and other quality characters.
