Abstract

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 seed coats in domestic black soybean. The seed of thirteen cultivars such as Geomjeongkong 1, Geomjeongkong 2, Seonheugkong, Tawonkong, Ilpumgeomjeongkong, Geomjeongolkong, 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 Seonheugkong 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-glucoside). Anthocyanin content of tested cultivars showed a high variation. The ranges of D3G, C3G, Pt3G, and TA (total anthocyanin) contents were $0.55\~2.63mg/g,\;2.77\~8.38mg/g,\;0.38\~5.65mg/g,\;and\;3.32\~16.92mg/g$, 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.

본 시험은 2001년부터 2002년까지 기능성 성분인 검정콩 안토시아닌에 대하여 종자내 개별색소 종류에 대한 검정과 함량 및 색차의 변이를 구명하여 특수콩 품종육성 및 재배 생리적 특성에 대한 기초 자료를 제공하고자 현재 국내에서 육성된 장려품종 및 재배품종인 검정콩1호, 검정콩2호, 검정올콩, 선흑콩, 흑청콩, 일품검정콩, 청자콩, 진주1호, 다원콩, 쥐눈이콩(G), 쥐눈이콩(Y), 검정콩3호, 검정콩4호를 공시하여 시험한 결과는 아래와 같다. 1. 검정콩 13개 재배품종의 개별 안토시아닌 검정에서 검정콩1호와 선흑콩이 cyanidin-3-glucoside(C3G)만 검출되었으며, 흑청콩은 delphinidin-3-glucoside(D3G)와 C3G가 검출되었고, 나머지 품종들은 D3G, C3G, petunidin-3-glucoside(Pt3G)가 모두 검출되었다. 2. 공시된 검정콩 재배품종의 안토시아닌 함량의 범위는 D3G가 $0.55\~2.63mg/g,$ C3G가 $2.77\~8.38mg/g$, Pt3G가 $0.38\~5.66mg/g$ 및 total anthocyanin(TA)이 $3.32\~16.67mg/g$이었으며, 품종간 및 연차간에 변이를 보였다. 3. 안토시아닌의 색차의 범위는 명도(L)가 $34.09\~42.89$, 적색도(a)가 $12.77\~22.85$, 황색도(b)가 $5.36\~12.79$이었으며, 품종간 및 연차간에 변이를 보였다. 4. 안토시아닌은 D3G, C3G, Pt3G 및 TA 모두 상호간에 고도의 정의 상관관계를 나타내었다.
