Daucus carota isolate:74,146: Daucus carota 74,146 Linkage Map for beta-Carotene Accumulation

The F4 population 74,146 was derived from a cross between USDA carrot inbred line B493, an orange-rooted inbred line, and QAL (Queen Anne’s Lace), a wild-type white-rooted carrot from the United States. This population was found to be segregating for root color (yellow, orange, or dark orange) associated with the Y2 locus. Genotyping by sequencing was used to find single nucleotide polymorphisms (SNPs) within individuals of this population.
