Abstract：This paper studies the genetic variations among one parental cultivar and it's five somaclonal variants. The experimental results show that variants have genetically stable variational characters. Some characters, such as the weight of grain, etc. are more steady in the variants than in the parental cultivar. Most variational characters are quantitations. Some characters such as the highness of plant, amylose, weight of grain are linked with the amount of protein, and the direction of variation may be positive or negative. Both dominant and recessive characters can be varied, and the most variation characters are the recessive. There is significant difference in anther culture ability among all cultivars. All variants, expect H28, have higher anther culture ability than that of H12, the parental material.
