摘　　要：通过利用国内外多个优质保持系亲本的杂交改良,选育审定了优质早籼三系不育系秋香A;并以目前国内外大面积推广应用的优质三系不育系金23A、新香A和T98A为对照,对秋香A的不育特性、异交特性、生育特性和形态特征等进行了比较研究;同时通过小面积繁殖制种和主要农艺性状的配合力试验,研究分析了秋香A的繁殖制种技术。Using some quality maintainer line parents collected from China and abroad to crossbreeding, a quality early hsien CMS line Qiuxiang A was selected and approved. The quality CMS line Jin23A, Xinxiang A and T98A were taken as control, which are popularization and application in a large scale in China and abroad at present, and a comparative study was conducted to sterile trait, outcrossing trait, growth trait and morphological trait between Qiuxiang A and control. Meanwhile, the techniques of propagation and seed production of Qiuxiang A were studied and analyzed through carrying out the combining ability experiments for propagation and seed production in a small area and main agronomic traits.
