Abstract

For the establishment of Distinctiveness, Uniformity and Stability (DUS) characterization, Twenty five landraces of rice (Oryza sativa L.), collected from different parts of Tamil Nadu, were characterized according to the DUS guidelines of the Plant Varieties Protection and Farmers’ Rights Authority, using thirty agro-morphological traits. Rice accessions were planted with three replications using the randomized block design (RBD) in 2021 at the Plant Breeding Farm, Department of Genetics and plant Breeding, Faculty of Agriculture, Annamalai University. Observations were recorded on various agro-morphological traits such as Leaf sheath, flag leaf, leaf blade, awns, panicle, ligure and clum characteristics. The results obtained revealed a wide range of variability for twenty five landraces, essential characters of the thirty DUS characters studied. The results of this study will be useful for restoration and conservation of beneficial genes. Contemporary research work will be advantageous for breeders to choose the right parent for crop improvement and the researchers for genetic diversity among landraces.
