摘　　要：龙特浦A配合力好,异交率、制种产量高,但育性不稳定.选用具有互补性状的地谷B、珍汕97B与其复合杂交,后代根据育种目标选株,与珍汕97A进行多代回交,选育出不育性稳定且基本保留龙特浦A优良特性的新不育系T55A,并已配制出T优5537、T优5570等强优势组合,具有较好的推广应用前景.Longtepu A is a broad using rice cytoplasmic male sterile line with high combining, outcrossing, and seed production ability, while its sterility is unstable. T55A, devived from Longtepu B multicrossed with Digu B and Zhenshan B, is a new CMS line with stable sterility and most of good traits of Longtepu A. Using T55A as parent material, the newly bred hybrids such as Tyou 5537, Tyou 5570 have very yielding ability and good prospect in practice.
