Abstract
Despite their medicinal, pharmaceutical, and nutritional importance of isoflavones, the genetic basis controlling the amounts of isoflavones in soybean seeds is still not well understood. The main obstacle is the great variability in the content of isoflavone in seeds harvested from different environments. In this study, quantitative trait loci (QTL) for the contentof different isoflavones including daidzein, genistein, and glycitein were investigated in a population of recombinant inbred lines derived from the cross of "Hwangkeum" (Glycine max) by "IT182932" (Glycine soja). Seeds analyzed were harvested in three different experimental environments. QTL analyses for isoflavone content were conducted by composite interval mapping across a genomewide genetic map. Two major QTL were mapped to soybean chromosomes 5 and 8, which were designated QDZGT1 and QDZGT2, respectively. Both loci have not been previously reported in other isoflavone sources. The results from this study will be useful in cloning genes that can control the contents of isoflavones in soybean and for the development of soybean lines containing a high or low isoflavone content.
