Description
Summary:The interest in phytochemicals from crops has grown in recent years, with soybean, as a functional crop, having great potential for providing a high level of nutrition. Therefore, the aim of this study was to evaluate phytochemicals from Korean soybean varieties, and to provide the basic information necessary for targeted breeding of soybean. The seeds of 172 soybean varieties were collected from various domestic institutes, and their phytochemicals were analyzed and compared based on agronomic characteristics (color, size, usage, etc.) using cluster analysis. We found that the soybean varieties contained relatively higher levels of the following phytochemicals: lutein (3 var., >7.0 [micro]g [g.sup.-1] seed), tocopherols (26 var., >300 [micro]g [g.sup.-1] seed), and phytosterols (33 var., >1000 [micro]g [g.sup.-1] seed). Overall, phytochemical levels were higher in varieties released since 2000 and with small-sized seeds (
