Nine flavonol glycosides occur in various soybean cultivars with gene t1 resulting in kaempferol and T1 controlling the presence of quercetin plus kaempferol (Buttery and Buzzell, 1973). The sugars of these glycosides have been identified and four flavonol glycoside genes have been studied (Buzzell and Buttery, 1973, and unpublished). A monoglucoside is the basic glycoside; it is present even when the four genes are recessive.
