摘　　要：统计分析了1973—2021年期间中国水稻两用核不育系的培育、两系法杂交水稻品种审定及推广应用情况。结果表明,截至2021年,全国共育成实用的水稻两用核不育系509个,选育出了一批两系法杂交水稻组合先后通过国家或省级审定,审定品种数量由“九五”期间的28个增加到“十三五”期间的1550个。农业农村部认定的两系法超级稻品种31个,略低于三系法超级稻品种数量,但在单个品种的推广面积上,两系法杂交水稻则明显高于三系法杂交水稻。The development of dual-purpose male sterile lines and the registration and application of two-line hybrid rice varieties in China during 1973—2021 were analyzed.The results showed that by 2021,509 dual-purpose male sterile lines had been developed nationwide,and a number of two-line hybrid rice combinations had been developed and approved for commercial production by the national or provincial crop variety appraisal committees,the number of registered varieties increased from 28 during the Ninth Five-year Plan period to 1550 during the 13th Five-year Plan period.The number of two-line super rice varieties identified by the Ministry of Agriculture and Rural Affairs is 31,which is slightly lower than that of the three-line super rice varieties,but in terms of the planting area per variety,the two-line hybrid rice is obviously higher than that of the three-line hybrid rice.
