| 摘 要： | 选用3个K型不育系及其保持系与5个恢复系组配杂交组合，研究K型细胞质对16个小麦主要性状的影响。结果表明：K型细胞质对普通小麦大多数性状有一定影响，但不同性状产生的效应不同，对农艺性状是不利影响，而对品质性状则是有利影响。主要表现在：株高变矮，分蘖成穗以及主茎小穗数和主茎穗粒数减少，千粒重和主茎穗粒重降低，导致产量的下降，子粒蛋白质含量和湿面筋含量则增加。但是，不同的不育系和恢复系所配的组合表现出的效应有很大差异．可以找到细胞质效应较小的不育系和恢复系材料。

| Abstract: | Three male sterile lines and their corresponding preserved lines,five restoring lines, and their hybrids were used to study effects of Ae. kotschyi cytoplasm on sixteen main traits of wheat. The results showed that Ae. kotschyi cytoplasm had different effects on different wheat traits. It was disadvantageous to agronomic traits, while it was advantageous to quality traits. Plant height was shortened. Yield decreased since ears and spikelets and grain number per culm decreased, and 1000-grain weight and grain weight per culm ear became lower. However, grain protein content and wet glutin content increased. Hybrids either of different male sterile lines or restoring lines had different responses, therefore, it is possible to choose a male sterile line and a restoring line with little cytoplasm effect. |
