본 연구의 목적은 국내에서 선발된 고 oleic acid 콩 품종인 광안콩의 환경안정성을 검토한 것으로 미국과 한국의 10개 환경에서 광안콩의 oleic acid 함량을 평가한 결과를 요약하면 다음과 같다. 1. 대조품종으로 이용된 고 oleic acid 콩 N98-4445A는 10개 환경에서 평균 55.5%의 oleic acid 함량을 보였고, M23은 47.4%의 함량을 보였다. 2. 광안콩은 고 oleic acid 대조품종 보다는 낮은 함량을 보였

Soybean [Glycine max (L.) Merr.] oil with high oleic acid (18:1) content is desirable for a broader role in food and industrial uses. Seed oil in commercially grown soybean genotypes averages about 23% oleic acid. Soybean accessions with elevated oleic acid content were reported by researchers. However, oleic acid concentration for some higher oleic acid genotypes can be affected by growing conditions. The objective of this study was to evaluate the stability of oleic acid concentration for soybean cultivar Kwangan with elevated oleic acid and typical oleic acid checks over ten environments. Oleic acid concentration of the high 18:1 checks N98-4445A and M23 ranged from 36.7 to 64.1% and 32.6 to 59.2% with averages 55.5% and 47.4%, respectively. However, oleic acid concentration of normal checks Williams 82 and 5002T ranged from 20.9 to 23.6% and 17.1 to 30.8% with averages 22.0% and 22.7%, respectively. Kwangan had an average 42.0% of oleic acid concentration with a range from 26.8 to 54.6% across ten environments. Kwangan showed relatively less stable than higher oleic acid genotypes, however it is a well adapted soybean cultivar in Korea therefore soybean cultivar Kwangan will be a good genetic source to develop increased oleic acid.
