Genetic Diversity of Soybeans (Glycine max (L.) Merr.) with Black Seed Coats and Green Cotyledons in Korean Germplasm

Soybeans (Glycine max (L.) Merr.) with black seed coats and green cotyledons are rich in anthocyanins chlorophylls known as functional nutrients, antioxidants compounds anticarcinogenic properties. Understanding the genetic diversity of germplasm is important to determine effective strategies for improving economic traits these soybeans. We aimed analyze 470 soybean accessions by 6K single nucleotide polymorphic loci architecture soybeans cotyledons. found showed narrow variability South Korea. The genotypic frequency d1d2 psbM variants cotyledon indicated that collections from Korea were intermingled Japan China. Regarding chlorophyll content, nuclear gene variant pair produced significantly higher a content than chloroplast genome variants. Among this study, flower color plays an role anthocyanin composition coats. provide 36 core collection representing 99.5% total used study show potential useful breeding materials cultivars
