In order to investigate the germination test and grouping of rice genotypes, an experiment was conducted in Khuzestan University of Agriculture and Natural Resources Laboratory in 1398. In this experiment, germination percentage, seedling fresh weight, seedling dry weight, root length, shoot length, germination weight index and longitudinal germination index were measured. The results showed that seedling fresh weight, shoot length, seed weight index were not significantly different. There was no significant difference between germination percentage, seedling dry weight, root length and weight index. Cluster analysis was performed to determine genotype grouping by Ward method. Cluster analysis on genotypes was used for each of the 7 traits and genotypes were divided into 4 groups by cutting the dendrogram.
