Variety Type: Breeding Population
The goal of breeding the Wisconsin Open Source Composite populations was to take commercially available cultivars that had freedom to operate for breeding and create diverse carrot populations based on market class and root color. These composite populations are meant to represent some of the diversity present in commercially available carrot germplasm that is available to use in breeding. The WI-OSC Purple population has purple exterior color (anthocyanin accumulation) with a variation of purple, orange, and white interiors. Roots are generally quite large in diameter with a significant taper. Tops are very vigorous. Parental material included: Cosmic Purple , Deep Purple, Dragon, Purple Haze, and Purple Sun. The roots in this population most clearly resemble the Cosmic Purple and Dragon varieties. This population has been developed for two generations under organic growing conditions.
