초록
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 17.1to 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.
Abstract
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 17.1to 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.
