Onion(Allium cepa L.) is one of the most important crops to the fresh vegetable spices and the food processing industry in Korea. To evaluate genetic variation in onion, major agricultural characteristics and biochemical characteristics such as flowering day, harvest day, brix and so on. Phenolic compound compositions were analyzed for 44 accessions. Accessions in white color was about 92% which is the largest one followed by standard criteria. The sweetness of juice ranged from 6.1 to 19.3(in brix), and Brix range of 117 accessions was from 10.1 to 14.0. High performance liquid chromatography(HPLC) was used to identify the phenolic profile and quantify phenolic content in bulbs: quercetin, quercetin 7, 4’-diglucoside, quercetin 3-glucoside and quercetin 4’-glucoside were detected as major components. The total Quercetin and Quercetin glycoside content ranged between 123.59 and 1155.84 mg/100mg bulb freeze dried weight. The quercetin contents was up to 16.7mg/100g, and 7.41mg/100g in average. It is expected that the result of this study can be used for breeding more competitive species with respect to contents in functional chemicals.
