영문 초록

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