Abstract:

Chhattisgarh is blessed with a wide variability in rice. Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh is proudly maintaining more than 23,000 rice germplasm accessions which is presently the largest active germplasm collection of rice in India and second largest in world. The present study was carried out by using 110 unique rice genotypes including one check. Morphological and grain yield related traits were studied to assess the existence of genetic divergence by using Non-hierarchical Euclidean cluster analysis. The 110 diverse genotypes were grouped into six distinct non overlapping clusters. Among the six clusters, cluster III is the largest cluster with a maximum of 33 genotypes followed by clusters I (20 genotypes) and cluster V & VI (18 genotypes each). Highest intra-cluster distance was observed in cluster IV, followed by cluster II and cluster V. It shows high variability among the genotypes of cluster IV. Highest inter-cluster distance was observed between cluster III & IV indicating that genotypes of these groups deserves consideration for their direct use as parents in hybridization programmes to develop high yielding rice varieties. It is followed by cluster I & IV. Cluster IV is characterized by genotypes with highest number of filled grains per panicle and total number of grains per panicle. Cluster III is having genotype with tallest plant height. Cluster II is having genotypes with high tillering capacity and yield which can be further utilized for trait specific studies.
