This research was done at seed and plant improvement research institute of Karaj . Iran . In this experiment “ Rondom Complet Block ” designe with four replications was used , and seventeen leaf characters on twenty of Iran apricot cultivars were studied .The aim of this research was to develop quantitative methods for description of the apricot cultivars . Morphological characters Including : Leaf Blade : (Length , Width , Ratio length/width , Intensity of green colour of upper side , Shape of base , Angle of apex ,Length of tip , Incisions of margin , Undulation of margin , Profile in cross section , Chlorophyll ) .Petiole : ( Length , Ratio length of blade/length of petiole , Thickness , Anthocyanin colouration of upperside , Predominant number of Nectaris ) .Weight of ten leaves . The name of cultivars as follows :BN-KB 21 , , BN-HS 524 , BN-RE527 , Jahangiri , Sharod 49 , Sharod 15 , Sharod 48 , BN-KB 29 , BN-KB 576 , Sharod 48 A , BN-KB 31 , Azgadi , BN-NO 512 , BN – KB 7, Sharod 31 , BN- SH 723 , Royal , Sharod 18 , BN-KB 40 , BN-KB 24 . As a result :The difference between cultivars is significant and the difference between leaf morphological characters will be used to distinguish of cultivars in Iran Apricots .
