BLACK JACK

Oil radish (Raphanus sativus)

Black number one

BLACK JACK is named after its distinctive black root. The variety has two nematode resistances, namely against Heterodera schachtii, category 1, and against Meloidogyne chitwoodi. Registered in Germany, BLACK JACK, a very late type, is the variety with the lowest tendency for flowering. This, combined with very slow and low growth, ensures that this variety has a very low to low tendency for lodging.
