Abstract

Two pairs of rDNA sites, with significantly different signal strength, were detected on two pairs of chromosomes of Pennisetum glaucum and P. violaceum. Both sites were physically located at the distal ends of the short arms of these two chromosome pairs, with the major pair being located on the two shortest chromosomes. Restriction fragment length polymorphism (RFLP) analysis enabled one of the two pairs of rDNA sites, designated Nor-P1, to be mapped on the fifth linkage group in Pennisetum.
