Quantum of genetic variability and the extent to which heritable and non-heritable variations are related to the characters, determines the extent of genetic amelioration. The present investigation was carried out in kharif, 2019 to understand the clustering pattern and correlation for yield attributing traits in aromatic landraces of rice. Here 90 aromatic rice landraces along with six check varieties were evaluated for 10 quantitative characters. Cluster analysis divided these 96 rice genotypes into 4 clusters. Highest inter cluster distance was observed between Cluster II and III suggesting maximum variability between them. Maximum heterotic crosses can be obtained by crossing between genotypes of Cluster II and Cluster III which can be used for rice improvement programme. Correlation analysis revealed that grain yield plant-1 was having positive and significant correlation with panicle weight, thousand grain weight and grain length indicating the importance of these traits for yield improvement. Selection on any of these characters will have a direct response on grain yield of aromatic rice.
