Somatic hybridization is a potential method for gene transfer from wild relatives to cultivated crops that can overcome sexual incompatibilities of two distantly related species.In this research,we analyzed the selfed and/or backcrossed progenies of the asymmetrical somatic hybrids between cauliflower (Brassica oleracea var.botrytis,CC,2n=18) and black mustard (B.nigra,BB,2n=16) by using morphological,cytological and molecular methods.Among 16 advanced selfing and backcrossing descendants in analysis,4 plants wereconfirmed having 9,16,16 and 18 cauliflower chromosomes added with 8,7,14 and 12 black mustard chromosomes respectively.
