This study was conducted to compare the agronomic traits of well-known colored native soybean germplasms. Recently, we are increasingly interested in colored as various functional ingredient of soybeans have revealed. We used a total of 396 soybean genetic resources, consisting of ten "Seonbijabikong", 110 "Jyinunikong", 276 "Seoritaekong". We sowed on 10th June 2018 at the field of Nongsaensmyeongro in Jeonju city. The average number of days to flowering, days to maturing and days to growth of colored soybean were 53, 84 and 136 days, respectively. Days to flowering of "Seonbijabikong" were ranged from 41 to 50 days with an average 48 days, those of "Jyinunikong" were ranged from 39 to 72 days with an average 52 days. Days to flowering of "Seoritaekong" were ranged from 35 to 63 days with an average 54 days, which were earlier in "Seonbijabikong", and similar with "Seoritaekong" and "Jyinunikong". Days to growth of "Seonbijabikong" were ranged from 125 to 137 days with an average 132 days, those of "Jyinunikong" were ranged from 91 to 144 days with an average 130 days and those of "Seoritaekong" were ranged from 99 to 150 days with an average 139 days. they were shortest in "Jyinunikong" and longest in "Seoritaekong". The distribution of maturity period was from 6th September to 5th November. The maturity period was as early as September and yields were more than 100g per plant, which were all three accessions(IT161905, IT162602, IT269617), "Seoritaekong". They would be useful as breeding materials of colored soybean with early maturity. The 100-seed weight is important characteristics that distinguish the usage of soybeans. "Seoritaekong" and "Seonbijabikong" have large seed characteristics for cooking with rice, "Jyinunikong" has small seed it for medicine. The average 100 seed weight was 35.0g of "Seonbijabikong", 30.8g of "Seoritaekong" and 13.4g of "Jyinunikong", respectively. As for seed coat lust, the ratio of dull was as high as 100% of "Seonbijabikong" and 91% of "Seoritaekong", that of shiny was as high as 77% of "Jyinunikong". Cotyledon color of "Seonbijabikong" were all yellow, that of "Seoritaekong" were 94% of green. The other name of "Seoritaekong" is "Sokcheong", which means that cotyledon color is green. Therefore if cotyledon color of Seoritaekong is not green, it might be misidentified. In the future, we will increase the utilization through evaluation of functional component such as isoflavones and anthocyanins of colored soybean landraces.

약용식물 느릅나무의 유전자원보존을 위하여 5개 자연집단을 대상으로 시과, 종자, 발아 및 생장특성에 대한 집단간 및 개체간 변이를 조사하였다. 전체 32개 개체목에서 시과를 채취하여 시과 및 종자특성(10개), 발아특성 (3개) 및 생장특성(2개)을 포함하여 총 15개의 특성을 분석하였다. 분산분석 결과 모든 특성에서 집단간 및 개체간에 고도의 유의적인 차이가 인정되었다. 평균특성을 살펴보면, 시과길이 13.0 mm, 시과폭 9.7 mm, 시과지수 1.37, 시과 무게 0.015 g, 과경길이 3.07 mm, 종자길이 3.85 mm, 종자폭 2.66 mm, 종자지수 1.46, 종자두께 1.29 mm, 종자무게 0.0062 g, 발아율 34.8%, 평균발아일수 8.6일, 발아속도 3.5개/일, 수고 37.7 mm, 근원경 4.90 mm로 나타났다. 특히, 시과무게, 발아율, 발아속도, 수고 및 근원경 특성은 집단간 및 개체간에 30% 이상의 높은 변이계수 값을 나타냈다. 느릅나무 집단간 유연관계는 지리적 분포에 따른 특별한 경향은 나타나지 않았으며, 유집군의 유형에 대한 주성분 분석 결과 제4주성분까지가 누적변이 값이 100%를 설명하였다. 제1주성분의 기여율은 41.8%로 형질간 상관분석에서 중요성이 높았던 인자들이었고, 제2주성분의 기여율은 32.9%로 발아특성이었으며, 제3주성분의 기여율은 16.3%로 생장특성이 느릅나무 집단간 유연관계에 중요한 정보를 주는 요인으로 나타났다.
