MORPHOLOGICAL TRAITS OF FOUR IRANIAN CERASUS

Iran contains significant wild genetic resources for many fruit species.
Those from the genus Prunus including cherries and their wild relatives (subgenus Cerasus) are among them.
Quantitative and qualitative traits of vegetative parts and seeds were used for categorizing cherry genotypes.
For this purpose, 28 wild genotypes from eight regions of Iran were studied.
These genotypes consisted of P. avium, P. mahaleb, P. incana and P. microcarpa. Cluster analysis indicated that tree height, leaf area, leaf shape, length of petiole, length of seed, seed weight, shape of seed tip and seed thickness were key characters.
The effective characters were grouped by seven factors that accounted for 85.71 of the total variance.
Cluster analysis was performed using seven factors and genotypes.
A distance 19 divided the samples into four groups consisting of the defined species.
A distance 10 defined eight smaller groups, suggesting intra-species regional differences.
Genotypes of same species from one region grouped together. Prunus mahaleb genotypes showed a high level of variance, indicating high biodiversity for Iranian cherries.
