‘BD6’ is a novel bred genotype derived from the walnut breeding program of the Research Institute for Fruit Growing and Ornamentals located in Budapest, Hungary. Because of its early budbreaking date, it needs warmer and safe fruit site conditions (small hills instead of flat sites). Female flowers of ‘BD6’ start to bloom earlier than the male flowers. It has a good and regular crop because of its intermediate fruiting pattern. Early ripening ‘BD6’ can start the Hungarian walnut season in the near future. Because of its very low susceptibility to walnut blight (Xanthomonos arboricola pv. juglandis), it can also be recommended as a donor for different breeding programs.
