Abstract: In order to study genetic diversity of the genotypes of peanut, an experiment was carried out with 23 genotypes of peanut by using randomized complete block design with three replications in the City Astaneh Ashrafieh, North of Iran at 2010. The results of the analysis of variance showed that there was significant difference between different genotypes in term of the plant height, total number of pods, total weight of pods, 100 pods weight, 100 seed weight, biomass (p<0.05) total number of seeds and seed yield (p<0.01). It is indicated that there is diversity between studied genotypes in respect of studied quantitative characteristics. Cluster analysis by using the method of average distance between groups, set 23 genotypes in 3 separate groups. Second cluster with 7 genotypes regarding yield components with yield of 3001.04 kg h-1 was allocated in first place compared to other cluster. Also, second and third clusters compared to first group had most characteristics with similar average and close to each other. There was the least distance between the genotype ICGV92267 and ICGV03060 and the most genetic distance between ICGV00441 and ICGV92033, there was for we can probably use these two genotypes in breeding programs in cross breeding as parents.
