Abstract
This research was conducted to study some vegetative and reproductive traits as well as qualitative and
quantitative characteristics and their correlation in 80 almond genotypes. Qualitative traits were studied
according 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 size
and 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 consumer
acceptance. The traits correlation showed that fruit, nut and kernel weight and size, had significant
positive 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 of
25, all genotypes were divided into two main branches. With decrease in the Euclidean distance from 25
to 5, the genotypes were divided into eight main subclusters. Cluster analysis revealed that the traits of
tree high and growth vigor, fruit, nut and kernel size and shell sofftness and hardness were the main
characteristics separating the genotypes.
