Almond is one of the most important fruit crops and the most important in the genus Prunus. Iran, due to a diverse variability in geographical regions such as mountain ranges and deserts spreading throughout the country and therefore diverse kinds of climates, is one of the origins of almond. In the current investigation, 174 almond genotypes were characterized using morphological traits to detect superior trees. Analysis of variance and coefficient of variation (CV) showed a high variability in the evaluated genotypes and significant differences were found between them for most of trait. Nut and kernel characters contributed most to the total variation. Also, the considered genotypes had significant differences in flowering and ripening time. Results from simple correlation analysis showed significant positive and negative correlations for certain important characteristics. Principal component analysis (PCA) showed high discrimination capabilities of variables measured. Genotypes 20, 119, 116, 43, 145, 168 and 171 were the best trees in terms of consistent high fruit set, large nut, large kernel, and late flowering time which can be singled out for cultivation. Furthermore, genotypes 28, 33, 129 and 171 were very-late flowering and could be useful as parents to cross for generating appropriate late flowering population or to improve flowering season of cultivars. Furthermore, two key variables including kernel weight and nut weight were the main variables accounting for kernel percentage and they should be considered together in breeding.
