Genetic improvement of rice genotypes for zinc deficiency tolerance and yield traits under aerobic condition is essential to exploit the water saving potential of aerobic condition. In the present study, sixty rice genotypes were raised under aerobic condition at Coimbatore, Tamil Nadu during dry season 2012-13 to identify the diverse genotypes. They were evaluated for eleven agronomic traits using D² to study the diversity pattern among the genotypes. Based on the analysis, the genotypes were grouped in to 7 clusters. Maximum numbers of genotypes (26) were grouped in cluster I. Cluster IV and VI consists of eight genotypes followed by cluster V and VII with seven genotypes. Clusters II and III were represented by two genotypes each. The maximum inter cluster distance was observed between cluster V and cluster VI (22.95) followed by between cluster III and cluster VI (20.56). Among the eleven traits studied, the traits viz., single plant yield, plant height, 100-grain weight, zinc score, plant harvest index, SPAD value and days to 50% flowering contributed 94.69% towards total divergence.
