Marker-assisted genotype analysis of bulb colors in segregating populations of onions (Allium cepa).

Molecules and cells - 30 Apr 2007

Abstract excerpt

Bulb color in onions (Allium cepa) is an important trait whose complex inheritance mechanism involves epistatic interactions among major color-related loci. Recent studies revealed that inactivation of dihydroflavonol 4-reductase (DFR) in the anthocyanin synthesis pathway was responsible for the color differences between yellow and red onions, and two recessive alleles of the anthocyanidin synthase (ANS) gene...
