摘　　要：辽宁是杂交粳稻的发源地,几代育种人在保留原有优势的前提下,不断进行种质资源创新,育出了以辽99A、辽105A、L6A、粳65A等为代表的优质不育系,这些不育系兼顾柱头外露、早花时等高异交特性,适用于机械化制种体系,其异交结实逐步提高,大面积制种稳定达到2625 kg/hm^(2),杂交粳稻新组合已经得到了广泛应用。Liaoning is the birthplace of japonica hybrid rice.Under the premise of retaining the original advantages,Liaoning Province has carried out continuous germplasm resources innovation,bred high-quality sterile lines represented by 99A,Liao 105A,L6A and Jing 65A,and gradually formed a mechanized seed production technology system.The outcrossing seed setting was gradually improved,and the large area seed production was stable to 2625 kg/ha.The new japonica hybrid rice combination has been widely used.
