     In this study, in order to evaluate important nutritional traits such as antioxidant activity, phenol, carotenoid, soluble and insoluble carbohydrates and iron and zinc contents, 35 different genotypes of rice were selected from native and foreign genotypes and evaluated in completely randomized design in 3 Repeats. For the results of cluster analysis, rice genotypes were classified in three groups and the grouping accuracy of 94.3 percent was obtained by discriminant analysis. In this grouping, according to mean of each group and percentage of deviation from total mean, appropriate and inappropriate groups were identified and the least amount of similarity was observed between groups two and three, which showed the difference between these two groups, the third group with Fajr, Gharib, Onda and IR64724-67-2-1-2-2R genotypes most appropriate and the second group with genotypes such as Amol 2, Danesh, Sadri, Mosa Tarom and Sepidrud inappropriate for nutritional value were identified in this study. Therefore, it can be suggested that these two groups can be used parents selection in breeding and hybridization programs. In factor analysis, four main and independent factors were identified that contributed 76.605 percent of total variances. The first factor with 27.542 percent of total variances was named as carbohydrate and zinc factors and the second, third and fourth factors with 18.169, 16.148 and 14.745 percent were named as phenol, antioxidant activity and iron factors, respectively.
