Fig. 4. Polymorphisms observed between NILs (L71-920 and L74-441) and their respective RP ‘Clark’ including the donor parent ‘Oni Hadaka’ using homologous gene sequence FCA as probe. DNAs were digested with a restriction endonuclease StyI. Arrows indicate polymorphic bands. Numbers on the left side of the picture indicate the lambda marker size in kilobase.
