Abstract: In order to screen specific RAPD markers of the gametocidal chromosomes and to investigate the DNA molecular polymorphism, 46 random primers were used in PAPD analysis of common wheat variety "Chinese Spring"-gametocidal chromosome additional lines and three Aegilops species as the donors of the gametocidal chromasomes. Products amplified with 35 of 46 primers were observed, and the specific RAPD markers of the three gametocidal chromosomes were determined, namely OPF-14₁₃₀₀ and OPQ-09₈₀₀ for chromosome 3C, OPF-14₁₁₆₀ and OPQ-09₇₇₀ for GCL and OPF-14₁₂₈₀ for 2C. In addition, 162, 140, 154 and 155 products amplified with 35 primers from common wheat "Chinese Spring", Aegilops triuncialis, A. Speltoides and A. cylindrica, respectively, and 69, 87 and 96 products are common to "Chinese Spring" and three Aegilops species, respectively. It was shown that close relationship in molecule level between common wheat and Aegilops is revealed.
