This study was carried out to get basic informations on utilization of castor bean for the production of biodiesel. A total of 68 genetic resources including 40 accessions obtained from the National Agrobiodiversity Center and 28 landraces collected in Korea were screened to evaluate seed characteristics, oil content, fatty acid composition and their relationships. One hundred and one liter seed weights ranged 20.1~37.1 g and 407.2~531.0 g with averages of 26.6 g and 481.1 g, respectively. Seed length and width ranged 10.1~14.9mm and 4.8~6.4mm with averages of 12.3mm and 5.7mm, respectively. Oil content ranged 41.6~57.2% with an average of 47.8%. Six accessions, IT032142, IT104010, IT104993, IT62783, CCB056 and CCB057, showed higher oil content than 50.0%. Palmitic and stearic acid contents, saturated fatty acid, ranged 0.9~1.8% and 1.0~2.1%, respectively. Oleic, linoleic, linolenic and ricinoleic acid contents, unsaturated fatty acid, ranged 3.6~6.5%, 4.7~7.3%, 0.5~1.2% and 82.5~88.7%, respectively. Oil, palmitic, stearic, oleic, linoleic and linolenic acid contents showed negative correlation with ricinoleic acid and unsaturated fatty acid contents, and showed positive correlation with saturated fatty acid content. Ricinoleic acid content showed negative correlation with saturated fatty acid content and positive correlation with unsaturated fatty acid content. Saturated fatty acid content showed negative correlation with unsaturated fatty acid content.
