Soybean [Glycine max (L.) Merrill] seed has poor storability under high temperature and high humidity. It loses viability in a relatively short time. Seed aging of stored soybeans leads to poor germination and a decrease in yield. The accelerated aging vigor test, which provides useful information for determining seed storability as well as field emergence potential, is a rapid aging experiment and could be used to determine soybean seed quality. This study was conducted to determine the seed viability of Korean soybean cultivars and soybean lines with altered fatty acid compositions under accelerated aging conditions. Results demonstrated that Songhagkong, a Korean soybean cultivar, was the most stable at 3, 4, and 5 days of accelerated aging conditions. Furthermore, two soybean lines with high stearic acid content exhibited >70.0% reduction rate, whereas three soybean lines with high oleic acid content exhibited 7.4%-11.8% reduction rates. Soybean lines with mid-oleic acid and elevated linolenic acid contents exhibited various reduction rates depending on genotypes. Therefore, these soybean lines can be used as breeding material for developing a new soybean cultivar with strong seed vigor and better storability under unfavorable conditions. Therefore, a genetic study on this soybean cultivar is warranted.
