A hundred landraces of rice (Oryza sativa L.), from core group genotypes collected from different parts of Chhattisgarh, were characterized following the guidelines from the Protection of Plant Varieties and Farmers' Rights Authority, GOI. Hundred rice accessions were planted in a randomized block design (RBD). The data were recorded on 30 different agro-morphological traits (19 qualitative and 11 quantitative). The rice germplasm exhibited sufficient genetic variation for most of the qualitative and quantitative traits. Variation was observed for all the qualitative traits except the presence of collar, auricles, and ligule. The descriptors offering the most discrimination were time to 50% heading, time to maturity days, thousand grain weight, stem length, grain length, and width. Out of 30 descriptors studied, five characteristics were found monomorphic rest of the characters show variations among the accessions. The genetic potential of the mentioned accessions for the desired traits can be utilized in future rice breeding programs to get promising results.
