This experiment was conducted to investigate the variation of anthocyanin, and isoflavone contents in five cultivars and two lines of Korean domestic black soybeans grown at different latitudinal locations, a high latitude, Suwon (37°16'N) and a low latitude, Milyang (35°30'N). Delphinidin-3-glucoside (D3G) contents of anthocyanin in Geomjeongkong No. 3 and Ilpumgeomjeongkong, cyanidin-3-glucoside (C3G) content in Milyang No. 113, petunidin-3-glucoside (Pt3G) contents in Milyang No. 113, and Ilpumgeomjeongkong, and total anthocyanins in Milyang No. 113 were highest among the seven black soybean cultivars and lines. D3G, C3G, and total anthocyanins in Geomjeongkong No. 3, C3G, and total anthocyanins in Ilpumgeomjeongkong grown at high latitude were higher compared to low latitude. Daidzein, glycitein, genistein, and total isoflavone contents in Geomjeongkong No. 4 were highest among the seven cultivars and lines. Daidzein contents of isoflavone in Geomjeongkong No. 3, Milyang No. 112, and Milyang No. 113 grown at high latitude were higher compared to low latitude. Glycitein contents in Geomjeongkong No. 3, and No. 4 grown at high latitude were higher compared to low latitude, while it in Milyang No. 113 grown at low latitude was higher compared to high latitude. Genistein contents in most black soybeans except Milyang No. 113, and total isoflavone contents in Geomjeongkong No. 4 and Cheongjakong grown at low latitude were higher compared to high latitude. The variations of anthocyanin except Pt3G and isoflavone contents seemed to be affected by environmental conditions like different latitude than the genotype because they showed the significant interaction between cultivars and locations.
