Abstract: DNA of gaoliang, wheat and millet transmited into the emoryo of purple rice by ciecompress osmosis. The purplerice produces variant plant which is about 0.36%, 1.5% and 2.5% in the combination of rice and gaoliang, rice and willet, rice and millet. The colours of variant plant tend to the acceptor or provider in the growing. The time of the earing is earlier or later than the contrast. The soluble protein electrophoresis belts of buds are also different.
