摘　　要：甘蓝型油菜光温敏核不育两用系N196S是利用杂交育种与系统育种相结合的方法经3年6个世代选育而成。N196S的育性随着温度升高、光照延长,由可育→部分不育→全不育,适宜南繁北制。A new PTGMS dual -use line N196S was bred through three years with six generations by a crossing and systematical breeding method. As temperature and light increased, the fertility of N196S changed from fertile→partly sterile→completely sterile. It is advisable to reproduce it in the south and to breed it in the north.
