Abstract

No white-flowered accession exists among the more than 1100 Glycine soja (Sieb. and Zucc.) accessions in the USDA Soybean Germplasm Collection, although one-third of the Glycine max (L.) Merr. accessions are white flowered. One white-flowered plant was found in G. soja accession PI 424008A growing in Stoneville, MS, in 1998. The objective of this research is to clarify the origin of this white-flowered plant. Phenotypic traits and DNA markers were used to compare the white-flowered line with the putative parental line, PI 424008A. The results from all of the data show that the white-flowered plant is very similar to PI 424008A, indicating that the white-flowered plant was produced by a mutation in PI 424008A. The white-flowered line has been added to the USDA Soybean Germplasm Collection and is designated as PI 424008C.
