In this study 17 accessions of colocynth from different parts of Iran cultivated in the research station of Horticultural Science Department of University of Tehran in randomized completely block design with three replications. Some morphological characters of fruits, total Phenol component, Carotenoid content and Fatty acid content were evaluated. According to results, the highest fruit number per plant and fruit yield was found in Orzooiyeh accession, While Khorasgan 5 accession showed the highest fruit weight. The highest amount of phenolic compound resulted in Kerman and Yazd accessions (88 µg g-1 d.m), and highest amount of Carotenoid in Arak and Ahvaz accessions (85 mg g-1 d.m.). The highest amount of linoleic acid was in Orzooiyeh accession seed (72.4%) and highest amount of oleic acid (13.8%) in Khorasgan 2 accession. In correlation analysis, fruit weight was relatively high correlated with central mesocarp and seed mesocarp diameter (r= 0.69). There was negative correlation between stearic acid amount and seed length, in the other hand longer seed had lower amount of stearic acid. In cluster analysis based on ward method at distance 5 accessions placed in 4 groups and one accession from Kerman segregated in separated cluster which had highest amount of total phenolic compound. Based on fruit traits and phytochemical compound variation could demonstrated that colocynth plants in Iran had high genetic diversity and there are possibility for crop up this plant based on yield and suitable growth.
