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 photo-thermal 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.

Key words: Non-photosensitivity, Extra-prematurity, Winter wheat variety Dongzao 5, Photo-thermal characteristics
