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。
The results showed that the introduced “683” had obvious photo-sterility characteristics and all of them were fertile and resistent under short-day (11h) conditions. The average self-seeding rate was 63.38% Under sunshine, the population of sterile plants was 100%, the average self-incompletion rate (sterility) was 99% or more, can be used for breeding. “683” is a middle-maturing type, which can be used to transfer new photo-sensitive CMS lines suitable for middle-late-maturing areas in Shanxi Province.
