2018 ASHS Annual Conference

Seeds from 38 cowpea accessions stored in the USDA, ARS, PGRCU freezer were evaluated for delphinidin, cyanidin, myricetin, quercetin content using high performance liquid chromatography (HPLC), and seed coat color. These flavonols and anthocyanins ranged from 0 to 1,378 ug/g in the cowpea seeds. Seed coat colors ranged from cream to black. This data will be subjected to an analysis of variance, mean separations, and correlation analysis to determine significant levels for the phytochemicals as well as interrelationships with chemicals and seed coat color. This information will assist breeders and other scientists in the development of cowpea cultivars with optimum levels of flavonols and anthocyanins.
