The results indicate that the alien cytoplasms of T. dicoccoides spont, T. dicoccum, Ae.longisima, Ae.squarrosa, Ae. cylindrica, Ae. ventricosa, Ae. crassa, Ae. juvenalis, Ae.vavilovii, Ae. speltoides, Ae. sharonensis, Ae. ovata and Ae. mutica possess better genetic efffects. The allen cytoplasms of Ae.ovata, Ae.speltoides, and so on, contain higher content of protein than the control ones. Therefore, they are valuable cytoplasmic materials for the heterosis of nucleus-cytoplasm hybrids. 异源细胞质 遗传效应 核质互作 农艺性状 allo-cytoplasm agronomic charaters genetic effect interaction of cytoplasm and nucleus 国家自然科学基金(61672102);国家“七五”攻关重点项目（75-02-02-02） 1991-03-01 2021-04-01 3
