通过农垦５８Ｓ／激光４号／／献党转育成的湖农５Ｓ，经研究属于籼型光敏核不育系。该不育系的主要特点是：不育起点温度低，达到了粳型光敏核不育系Ｎ５０８８Ｓ的水平，制种安全可靠；转为可育的临界光长要求比Ｎ５０８８Ｓ更短，在湖北不能繁殖，需在低纬度地区冬季繁殖；它柱头外露率高，开花习性较好，有利制种；配合力强，其杂种米质好，抗性较强，可以这配出强优势组合。
Through the Nongken 58S / Laser 4 / Donor Party into the lake farmers 5S, the research belongs to indica-type photosensitive nuclear sterile line. The main features of the CMS are: low starting point of sterility, reaching the level of japonica photo-sensitive genic male sterile line N5088S, seed production is safe and reliable; the critical light length to fertile requirement is shorter than N5088S, Reproduction, the need to breed in low latitudes in winter; its stigma exposed rate is high, flowering habit is better, favorable seed; strong combination, the hybrid rice is good, strong resistance, which can be allocated a strong combination of advantages.
