| 摘 要： | 以强冬性小麦品种京冬8号为对照，采用分期播种试验，分析了非光敏特早熟小麦新品种冬早5号的生长发育进程和光温特性，并探讨了播期对两种小麦品种生育期和产量的影响.结果表明，冬早5号小麦品种比对照品种京冬8号早熟3～4 d，标准播期增产43.4%.冬早5号小麦品种在低温、短光照条件下也能完成正常的穗分化进程，其每经历一个穗分化期Z所用的天文日照时数、有效积温和光温积明显少于京冬8号.该品种在穗分化阶段对光照不敏感，无需经过严格的春化阶段和光照阶段，品种类型介于冬性和春性之间，冬前适播期较广，适合秋播也可以春播，这在小麦育种领域是个突破. |

| Abstract: | 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. |
| Keywords: | Non-photosensitivity Extra-prematurity Winter wheat variety Dongzao 5 Photo-thermal characteristics |
