재배연도에 따른 검정콩 종자의 안토시아닌 함량 및 색차변이

This research was carried out to offer the basic informations about new varietal breeding for specific use and physiological characteristics through investigation of detection, content variation and color difference of anthocyanin individual pigments within seedcoats in domestic black soybean. The seed of thirteen cultivars such as Geomjeongkong 1, Geomjeongkong 2, Seon- heugkong, Tawonkong, Ilpumgeomjeongkong, Geomjeon- golkong, Cheongjakong, Jinju 1, Heugcheongkong, Juinunikong-Y, Juinunikong-G, Geomjeongkong 3, Geomjeongkong 4 was tested. C3G (cyanidin-3-glucoside) was detected in only Geomjeongkong 1 and Seon- heugkong but D3G (delphinidin-3-glucoside) and C3G were found in Heugcheongkong. The rest cultivars that there were three anthocyanins such as D3G, C3G, and Pt3G (petunidin-3-gIucoside). Anthocyanin content of tested cultivars showed a high variation. The ranges of D3G, C3G, Pt3G, and TA (total anthocyanin) contents were 0.55 ~ 2.63 mg/g, 2.77 ~ 8.38 mg/g, 0.38 ~ 5.65 mg/g, and 3.32 ~ 16.92 mg/g, respectively. These contents showed variation among cultivars as well as variation between two years, 2001-2002. As a result of variation of anthocyanin color difference, the ranges of L (lightness), a (redness), and b (yellowness) as Hunter's value were 34.09 ~42.89, 12.77 ~22.85, and 5.36 ~12.10, respectively, and these color differences showed variation among cultivars and also variation between two years, 2001-2002. D3G, C3G, Pt3G, and TA showed reciprocally a positive correlation being representive of high significance.
