Abstract: Taken the winter wheat variety Jingdong 8(JD8) with the strong winter hardiness as CK,the field experiment was conducted to study the growth characteristics before winter,winter hardiness and yield constitution of the new winter wheat variety Dongzao 5(DZ5),one of the non-photosensitive and extreme early mature wheat variety.The results showed that the critical temperature for mortality(LT50) of DZ5 was(-(14.9℃)),it is 1.8℃ higher than that of JD8,and it is a weak winter hardiness winter wheat variety.The harvest date of DZ5 was 4 days earlier and its yield was 43.4 % higher than that of JD8.DZ5 could over-winter safely in Beijing and the south areas of Beijing.
