Comments about the QTL

QTL only described in figure with location and LOD score; no other information given

The trait measured was the content of the isoflavone genistein in seeds. Genistein content was determined by High Performance Liquid Chromatography (HPLC) and quantified as micrograms of genistein per gram of dry seed weight
