摘要
观察结果表明，引进的“683”具有明显的光敏不育特性，在短日照（11h）条件下，全部恢复可育，平均自交结实率为63．38％，可以繁种；在长治春播自然日照下，群体不育株率为100％，平均自交不实率（不育度）为99％以上，可用于繁种。“683”属中早熟类型，可用于转育适宜山西省中晚熟区利用的新光敏不育系。
Through observation we find out that '683' introduced has the character of obvious photo-period-sensitive male-sterile. In short light day (11h), it recovers its fertility all. The average selffertility percentage reaches 63. 38%. When '683' is spring sowed in natural day in chang zhi, the rates of sterile plants reaches 100% and average seed sterility above 99%. Its major characters are stable and it may be used to breed seeds. '683'belongs to the type of middle-early matkure and we may change its fertility and breed new type of photoperiod-sensitive sterile line for suiting middle-late mature areas in our province.
