Seed Characteristics of Black Soybean Collections in Korea

수집재래 검정콩의 종실특성

The improvement of superior black soybeans could be accomplished through maintenance and use of black soybean collections. A collection of 965 black soybean lines currently grown by farmers was made in 197 locations on spring, 1991. This study was carried out to evaluate them as useful germplasm. Seed characteristics of black soybean collections were evaluated for black soybean breeding for seed quality. The 100-seeds weight of 929 black soybean genotypes were distributed from 6.9 to 48.1 gram. The maximum and minimum 100-seeds weight were derived from Chungnam and Jeonbuk province, respectively. l00-seeds weight was heavier in middle and late maturity group, as maturity was later, whereas no tendency was shown in early maturity group. Length, width and thickness of the collected black soybean seeds were 9.5$\pm$1.5mm, 7.3$\pm1.3mm and 7.3$\pm1.2mm, respectively. Black soybean collections with yellow seed embryo was 72% and the others were green seed embryo.

양질의 밥밑콩 품종 육성 및 유전자원으로의 활용가능성을 검토하고자 전국에서 수집한 검정콩 965계통을 대상으로 종실의 외형적 특성과 그 분포를 조사한 바 그 결과를 요약하면 다음과 같다. 1. 수집검정콩 계통의 100립중 전국평균은 28.1g이었으며 도별 변이를 보면 경기도와 경북 수집 계통이 무거웠으며 전북, 전남지역이 가볍게 나타났다. 2. 성숙군별 100립중의 차이는 중, 만숙군에서는 성숙군이 늦을수록 100립중이 무거웠다. 3. 수집검정콩 종실의 입형은 대체로 타원형이었으며 길이:폭:두께 비율의 평균은 1:0.77:0.77이었다. 4. 수집검정콩의 자엽색 분포에서는 72%가 황색자엽이었으며 27%가 녹색자엽이었다.
