Abstract: The purpose of the experiment is that, Four alloplasm of Triticum aestivum cv, Chinese Spring With the cytoplasms of Aegilops, that is,T. Zhukovskyi(G type), Ae. Crassa(D² type), Ae. Mutica(M^t type)and Ae. variabilis(S^v type), were used as female paren. which respectively were crossed with male parent Ha shi one (AABBDD), All the nuclear genotype of F1 hybrid generation were compele the same. Under this condition, according to the difference among the character of F1 generation, we can discuss the effect of cytoplasm.

Key words: Wheat, Allplasm, Effect
