发现并系统观察了棉花雄性不育材料晋Ａ。通过镜检、自交、测交、回交、开放授粉和网罩试验表明，此材料不育性完全而稳定，陆地棉品种可作其完全保持系，海岛棉品种可使其育性恢复，是我国新发现的又一质核不育材料。其不育胞质来自陆地棉，但与其它胞质系不同。这一发现为棉花三系配套、实现产量上的突破提供了新的胞质基因源
Found and systematically observed the cotton male sterile material Jin A. Through microscopic examination, selfing, cross test, backcrossing, open pollination and net cover test, the sterility of this material was completely and stably maintained, and the upland cotton variety could be used as its complete maintainer. The island cotton variety could restore its fertility, It is another newly discovered nuclear sterile material in our country. The sterile cytoplasm comes from upland cotton, but different from other cytoplasm. This finding provides a new source of cytoplasmic genes for cotton three-line package to achieve a breakthrough in yield
