야생콩(Glycine soja Sieb. & Zucc.) 유전자원의 단백질, 지방 및 지방산조성 변이

This study was carried out to obtain useful information and to select promising materials for the breeding of sprout-soybean by the analysis of seed characteristics and chemical composition of Korean local wild soybean lines. For this purpose, crude protein, crude oil contents and fatty acid composition of 70 lines analysed. The crude p1ηtein content of Korean wild soybean lines ranged from 35.6 to 47.9%, mean was 42.34%, and 13 lines showed high protein content over 45%. The crude oil content of those ranged from 2.8 to 18.0%, mean was 10.2%, and 2 low lines were below 2%. The fatty acid 16:0, 18:0, 18:1, 18:2, 18:3 ranged 11.1-44.6%, 3.0-11.4%, 11.1-30.6%, 12.4-59.5%, and 1.1-17.3% respectively, and 2 extremely low fatty acid(18:3) lines were selected. Significant correlation between crude oil and fatty acids(16:0, 18:0, 18:2), and among every fatty acid compositions were recognized. Promising wild soybean Lines were selected as genetic resources for sprout-soybean breeding and research genotypes; YWS 104 and YWS189 as the high protein, YWS 28 and YWS30 as the low-crude oil and low 18:3.
