摘　　要：1892S是安徽省农业科学院水稻研究所用培矮64S的窜粉变异单株选育的中籼光温敏核不育系,2004年8月通过安徽省技术鉴定。1892S具有配合力高、可繁性好、异交率好、制种产量高、抗性强、米质优等特点。所配组合杂种优势强,具有耐肥抗倒、适应性广等优点。该研究介绍了1892S的选育经过、育性表现、特征特性、系列品种示范推广情况,为籼型光温敏核不育系1892S及系列组合的推广应用提供理论依据。1892S is a indica PTGMS lines bred with Pei＇ai 64S by Rice Research Institute of Anhui Academy of Agricultural Sciences, and pass through the technical appraisal in Anhui Province in Aug. 2004. 1892S has high combining ability, good reproductive ability, outcrossing rate, high seed production yield, strong resistance, good quality ; the combination has the advantages of strong heterosis, resistance to fat and lodging and wide adaptability. The breeding course, fertility performance, characteristics＇ demonstration and extension of series varieties of 1892S were introduced, which will provide theoretical basis for promotion and application of 1892S and combination.
