The present investigation was carried out with 24 rice genotypes including both indigenous and exotic collections/varieties/lines under both normal transplanted condition and in submerged condition and observation for various morphophysiological, quantitative and qualitative traits by using randomized block design at the Research Farm of ‘Tirhut College of Agriculture, Dholi, Dr Rajendra Prasad Central Agricultural University, during Kharif season of 2019. All the 24 genotypes grouped into 3 clusters using D2 statistics. Intra cluster distance was at most in case of Cluster II while highest inter cluster distance was detected between Cluster III and Cluster II. Cluster III contains maximum yield attributing traits so it can be used for hybridization programme of above-mentioned traits. Crop Growth Rate at 30DAS showed maximum contribution towards total divergence while minimum contribution was exhibited by Number of Fertile Spikelet.
