摘要
利用单芒山羊草、粘果山羊草小麦细胞质雄性不育系，和其同型保持系各４个品系与１０个普通小麦品系杂交，研究其Ｆ１杂种的农艺性状效应。结果表明：单型细胞质与Ｋ型细胞质在农艺性状上的效应基本一致，但单型细胞质杂种较Ｋ型杂种种子发芽率提高。单型细胞质抗白粉病能力可能较Ｋ型好。
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.
