１９８０年以农垦５８Ｓ为光敏核不育基因供体，与国内外粳稻品种（系）杂交，经多代连续选择，育成一批具有不育性稳定、育性转换明显、开花习性好、易繁殖制种、抗病性较强、配组优势明显的模型光敏核不育系。用其配制的组合Ｎ５０４７Ｓ／Ｒ９－１和Ｎ５０８８Ｓ／Ｒ９－１等，１９９２年示范面积达３万余亩，并获得初步成功。
In 1980, Nongken 58S was used as a donor of photoperiod-sensitive genic male sterility and crossed with japonica varieties at home and abroad. After several generations of continuous selection, a group of plants with stable sterility, obvious fertility transformation, good flowering habits and easy breeding Seed production, disease resistance, with obvious advantages of the model photosensitive male sterile line. With its preparation of the combination of N5047S / R9-1 and N5088S / R9-1 and so on, in 1992 demonstration area of 3 million mu, and achieved initial success.
