Ae.Uniaristata cytoplasm wheat male sterile (CMS) lines,4 Ae.Kotschyi CMS lines and their maintainer lines were crossed with 10 common wheat lines.The agronomic characters were investigated.The result indicated that there were no significant difference between the effect of U type cytoplasm and K type cytoplasm on almost all agronomic characters, while the U type cytoplasm increased seed germination rate. The U type cytoplasm might have better resistance to powdery mildew.
