Abstract Restriction fragment length polymorphism (RFLP) and the structure of ribosomal RNA genes (rDNA) were investigated in 117 landraces of foxtail millet, Setaria italica (L.) P. Beauv. Five RFLP phenotypes were found when the genomic DNA was digested with BamHI; these were named types I–V. Of these types I, II and III were the most frequent. Type I was mainly distributed in the temperature zone, type II in the Taiwan-Philippines Islands and type III in South Asia. Restriction mapping of the cloned rDNA and comparison with RFLP phenotypes showed that the different types originated from a polymorphism in the length within the intergenic spacer (IGS) and BamHI site changes within the IGS.
