An experiment was carried out with 48 elite rice genotypes to study genetic diversity for direct seeding traits. They were evaluated for 19 characters consisting of 13 agronomical and six physiological using Mahalanobis D2 statistics. On the basis of D2 values the genotypes were grouped into eight clusters. Cluster I and VI were the largest containing 15 and 12 genotypes respectively followed by cluster III with 6 and cluster V with 4 genotypes. The maximum inter-cluster distance was recorded between clusters VII and VIII (11832.91) and the maximum intra-cluster distance was found in cluster IV (841.80) followed by cluster III (823.07). The characters like test weight (46.99%), vigour index (34.57%), plant height (12.23) and number of total grains panicle-1 (1.68%) contributed maximum towards genetic diversity. Therefore these characters could be given due importance for selection of genotypes suitable for direct seeding in rice. Genotypes from the clusters VII and VIII, III and VIII, I and VIII will result in superior segregants.
