Abstract

A total of 135 black seeded soybeans genotypes were collected in 45 island locations from January to May 2001. Seeds of 135 genotypes collected were analyzed for crude protein and fatty acid compositions. The crude protein content was averaged to be 40.75%, and was ranged from 34.70% to 44.20%. The average palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid content were 11.41%, 3.93%, 22.75%, 53.55%, and 8.35%, and the ranges of those were 9.00% to 14.40%, 2.90% to 5.00%, 22.75% to 26.50%, 50.30% to 57.20% and 6.7% to 11.20%, respectively. Heritabilities of palmitic acid, oleic acid, linoleic acid, and crude protein were higher, but that of stearic acid and linolenic acid were relatively lower, Crude protein content was correlated positively with oleic acid content, whereas it was correlated negatively with linoleic acid, palmitic acid, stearic acid, and linolenic acid contents.

서남해안 부근의 섬에서 재배되고 있는 재래종 검정콩 유전자원 45품종(135점)의 조단백, 지방산 조성을 분석한 결과 조단백 함량 변이는 34.70-44.20%(평균 40.75%),지방산 조성 변이는 palmitic acid에서 9.00-14.40%(평균 11.41%) stearic acid에서 2.90-5.00%(평균 3.93%), oleic acid에서 22.25-26.50%(평균 22.75%), linoleic acid에서 50.30-57.20% (평균 53.55%), linolenic acid에서 6.70-11.20%(평균 8.35%)의 변이를 보였다. 지방산에 대한 유전력은 oleic acid에서는 높았으나 stearic acid와 linolenic acid에서는 낮았으며 palmitic acid, linoleic acid는 조단백의 유전력과 같은 경향으로 중정도 이었다. 형질상호간의 상관 계수에서 조단백은 oleic acid와는 고도의 유의차로 정의 상관을, linoleic acid와는 고도의 유의 차로 부의 상관을 보였고 기타의 지방산간에는 부의 상관을 보였다.
