This research was conducted to study some vegetative and reproductive traits as well as qualitative andquantitative characteristics and their correlation in 80 almond genotypes. Qualitative traits were studiedaccording to gulcan descriptor. Quantitative traits were analyzed as completely randomized design(CRD), with 12 replications. The results showed that genotypes had significant difference in fruit, nut,kernel weight and kernel to nut weight ratio. No169 genotype was very late blooming and had large sizeand moderate quality fruits. Fruit, nut and kernel weight in this genotype were 12.50, 4.75 and 1.28,respectively. Kernel of this genotype was sweet with low shriveling, which are important of consumeracceptance. The traits correlation showed that fruit, nut and kernel weight and size, had significantpositive correlation together. Also, kernel taste had significant negative correlation with pubescence,shriveling and color intensity of kernel. Results of cluster analysis showed that, in Euclidean distance of25, all genotypes were divided into two main branches. With decrease in the Euclidean distance from 25to 5, the genotypes were divided into eight main subclusters. Cluster analysis revealed that the traits oftree high and growth vigor, fruit, nut and kernel size and shell sofftness and hardness were the maincharacteristics separating the genotypes.
