摘要
ＣＧ１７Ｓ在宁夏自然条件下有明显的不育期、可育期、育性转换期。育性转换的临界温度为２５．５℃，育性转换的敏感期为抽穗前２０～２５ｄ。育性主要受敏感期平均温度的影响，其次为最低温度。ＣＧ１７Ｓ在宁夏自然条件下有合适的制种时间区段，有较好的应用前景。
Under the natural conditions of Ningxia CG17S had clear sterile,fertile and fertilitytransitionary period.The fertilitytransition of CG17S was found influenced mainly by temperature and the critical temperature was 25.5℃.The sensitive stage of fertilitytransition occured 20-25 days before heading.Based on the performance of fertility of CG17S in Ningxia,there are proper areas suitable for the production of its hybrid seeds and areas optimal for its multiplication.
