Table 2 Segregation of flower color in F3 lines derived from a cross between a soybean near-isogenic line Clark-w1 with white flowers and B09121, a Glycine soja accession with light purple flowers in Tsukuba, Japan in 2008.

From: A new allele of flower color gene W1 encoding flavonoid 3'5'-hydroxylase is responsible for light purple flowers in wild soybean Glycine soja
