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, 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 0.55~2.63 ㎎/g, 2.77~8.38 ㎎/g, 0.38~5.65 ㎎/g, and 3.32~16.92 ㎎/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. 적 요 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 0.55~2.63㎎/g, C3G가 2.77~8.38㎎/g, Pt3G가 0.38~5.66㎎/g 및 total anthocyanin(TA)이 3.32~16.67㎎/g이었으며, 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 5.36~12.79이었으며, 품종간 및 연차간에 변이를 보였다. 4. 안토시아닌은 D3G, C3G, Pt3G 및 TA 모두 상호간에 고도의 정의 상관관계를 나타내었다.

The purpose of this experiment was to obtain informations about variation of anthocyanin content within black-seeded soybean testa according to planting dates, varieties, and growth stages. Three varieties, Ilpumgeomjeongkong, Geomjeongkong 2, Tawonkong were tested in this experiment. Seeds were planted on April 15 (early planting), May 15 (optimum planting), and June 15 (late planting), respectively. Growth stages were R6 (full seed), R7 (physiological maturity), and R8(harvest maturity). The content of delphinidin-3-glucoside (D3G), cyanidin-3-glucoside (C3G), petunidin-3-glucoside (Pt3G), and total anthocyanin (TA) had all increased gradually from April 15 to June 15 as well as R6 to R8. There was no varietal difference in D3G, but C3G and TA of Geomjeongkong 2 were higher than other two varieties. Pt3G was the highest in Tawonkong. The value of L as anthocyanin color difference had gradually decreased from April 15 to June 15 and R6 to R8, Geomjeongkong 2 among three varieties was the lowest. The value of a was the highest on May 15 and increased gradually from R6 to R8, Geomjeongkong 2 was the lowest. The value of b was the highest on June 15 as late planting and Geomjeongkong 2 was the highest. The value of b had increased gradually from R6 to R8. D3G, C3G, Pt3G, and TA contents showed mutually high positive correlation and these four characters were represented high negative correlation with L value but showed high positive correlation with a and b values. The value of L showed high negative correlation with a and b values. The value of a showed high positive correlation with b value. 본 시험은 파종기, 품종 및 생육단계에 따른 검정콩 종자내에 함유된 기능성 물질인 안토시아닌의 함량 및 색차의 변이에 대한 정보를 얻고자 재배품종 중 일품검정콩, 검정콩2호와 다원콩을 공시하였으며, 파종기는 4월15일, 5월 15일 및 6월 15일로 하였고, 생육단계는 R6(종실비대성기), R7(생리적 성숙기) 및 R8(수확적성숙기)로 하여 수행한 결과는 다음과 같다. 1.

To proffer the basic data about varietal breeding for specific use through investigation of the content and color difference of anthocyanin due to seed sizes and cotyledon colors. Eight varieties, Geomjeongkong 2, Ilpumgeomjeongkong, Geomjeongolkong, Cheongjakong, Tawonkong, Jinju 1, Juinunikong-Y, and Juinunikong-G were tested in this experiment. Delphinidin-3-glucoside (D3G), petunidin-3-glucoside (Pt3G), and total content of anthocyanin were higher in small seeds but cyanidin-3-glucoside (C3G) was not different between seed sizes. Color difference of anthocyanins between large and small seeds was no distinguished difference in L (lightness), a (redness), and b(yellowness) as Hunter's value. D3G and PT3G in seed cotyledon color were higher in yellow color than green color and C3G and total content were higher in green color than yellow color. The L, a, and b of anthocyanin between seed cotyledon colors were all not different.

This experiment was conducted to investigate any change in chemical properties of soil as well as growth and yield components of Seokryangputkong cultivated is vinyl house mainly used for consecutive cultivations of vegetables. Seokryangputkong, a recommended variety as a vegetable soybean by Rural Development Administration in 1995, was planted 4 times from April 15 to May 15 in 10 days - interval in vinyl house in Such`ang-ri, Choch`iwon-up, Yunki-gun, Chungnam, the analysis of the chemical properties of the soil indicated that available P₂O₂ content, EC, organic matter content and Ex-Na were increased by 89.3mg/kg, 0.1dS/m, 0.1% and 0.1me/100g, after a cultivation of vegetable soybean, respectively. Whereas, Ex-Ca and Fx-Mg were decreased by 1.2me/100g and 0.1me/100g, respectively and pH and Ex-K were not changed. Emergence date, days to emergence and average emergence period were shortened as planting delayed in 10 days - interval from April 15. There was no difference shown in emergence rate in different planting dates. Days to flowering, pod formation and maturity were respectively shortened by 8.3 days, 2.7 days and 11.4 days as planting dates delayed in 10 days - interval from April 15. Days to flowering was not significantly correlated with days to pod formation but it showed a highly positive correlation with days to maturity. Days to pod formation showed a highly positive correlation with days to maturity, too. Stem height, stem diameter, number of stem nodes, number of branches, number of branch nodes and internode length of cotyledon were reduced as planting dates delayed, and fresh weight per plant did not show any difference as planting dates delayed. The number of unfilled and one - seed pods per plant were reduced as planting dates delayed, and number of two - seed and three - seed pods per plant, number of pods per plant and fresh weight per plant did not show any difference as planting dates delayed. Pod length and pod width showed some difference in different planting dates but there was no difference in pod thickness. The number of seeds per plant, seed weight per plant, one hundred - seeds weight, seed length and seed width were not different among planting date. Seed thickness was reduced as planting dates delayed. Among the various characteristic, stem diameter showed a highly positive correlation with seed thickness. The number of branches and branch nodes showed a highly positive correlation with one hundred - seeds weight and seed thickness. The number of pods per plant showed a highly positive correlation with fresh weight per plant and pod length. the number of one-seed per plant showed a highly positive correlation with fresh weight per plant, fresh weight of pods per plant and weight of seeds per plant Fresh weight of pods per plant showed a highly positive correlation with weight of, seeds per plant One hundred - seeds weight showed a highly positive correlation with seed width and seed length showed a highly positive correlation with seed width. The other characteristics did not show any significant correlation reciprocally.
