In a sowing by stages test with winter wheat variety Jingdong 8 (JD8) as reference, this paper studied the photothermal characteristics of a non-photosensitive and extra- premature winter wheat variety Dongzao 5 (DZ5), and the effects of sowing stages on its growth and yield. The results showed that the harvest date of DZ5 was 4-5 days earlier than that of JD8, and its yield with standard sowing date increased by 43.4%. In addition, DZ5 had a shorter thermoperiod for ear differentiation, and didn't need strict vernalization process and photoperiod, which could be sown either before or after winter.
