从水稻双胚苗群体中筛选出来的自然发生的四倍体和正常的二倍体进行杂交，在早世代获得了在田间表现稳定的群体，用微卫星分子标记验证了早世代群体在遗传上的稳定性，并对这种现象的机理进行了讨论，认为这一个特殊现象的发现对水稻的理论研究和育种实践都具有重大的意义。
Naturally occurring tetraploids and normal diploids selected from the rice double embryo population were crossed to obtain stable populations in the field in the early generation. Microsatellite markers were used to verify that the early generation population was genetically The mechanism of this phenomenon was discussed, and the discovery of this particular phenomenon was of great significance to the theoretical research and breeding practice of rice.
